"The SUSE Linux Enterprise 12 SP1 kernel was updated to receive various
security and bugfixes.

The following security bugs were fixed :

CVE-2018-12207: Untrusted virtual machines on Intel CPUs could exploit
a race condition in the Instruction Fetch Unit of the Intel CPU to
cause a Machine Exception during Page Size Change, causing the CPU
core to be non-functional.

The Linux Kernel KVM hypervisor was adjusted to avoid page size
changes in executable pages by splitting / merging huge pages into
small pages as needed. More information can be found on
https://www.suse.com/support/kb/doc/?id=7023735 CVE-2019-11135:
Aborting an asynchronous TSX operation on Intel CPUs with
Transactional Memory support could be used to facilitate sidechannel
information leaks out of microarchitectural buffers, similar to the
previously described 'Microarchitectural Data Sampling' attack.

The Linux kernel was supplemented with the option to disable TSX
operation altogether (requiring CPU Microcode updates on older
systems) and better flushing of microarchitectural buffers (VERW).

The set of options available is described in our TID at
https://www.suse.com/support/kb/doc/?id=7024251 CVE-2019-16233:
drivers/scsi/qla2xxx/qla_os.c did not check the alloc_workqueue return
value, leading to a NULL pointer dereference. (bsc#1150457).

CVE-2019-10220: Added sanity checks on the pathnames passed to the
user space. (bsc#1144903).

CVE-2019-16232: Fix a potential NULL pointer dereference in the
Marwell libertas driver (bsc#1150465).

CVE-2019-16234: iwlwifi pcie driver did not check the alloc_workqueue
return value, leading to a NULL pointer dereference. (bsc#1150452).

CVE-2019-17055: The AF_ISDN network module in the Linux kernel did not
enforce CAP_NET_RAW, which meant that unprivileged users could create
a raw socket (bnc#1152782).

CVE-2019-17056: The AF_NFC network module did not enforce CAP_NET_RAW,
which meant that unprivileged users could create a raw socket
(bsc#1152788).

CVE-2019-16413: The 9p filesystem did not protect i_size_write()
properly, which caused an i_size_read() infinite loop and denial of
service on SMP systems (bnc#1151347).

CVE-2019-15902: A backporting issue was discovered that re-introduced
the Spectre vulnerability it had aimed to eliminate. This occurred
because the backport process depends on cherry picking specific
commits, and because two (correctly ordered) code lines were swapped
(bnc#1149376).

CVE-2019-15291: Fixed a NULL pointer dereference issue that could be
caused by a malicious USB device (bnc#11465).

CVE-2019-15807: Fixed a memory leak in the SCSI module that could be
abused to cause denial of service (bnc#1148938).

CVE-2019-14821: An out-of-bounds access issue was fixed in the
kernel's KVM hypervisor. An unprivileged host user or process with
access to '/dev/kvm' device could use this flaw to crash the host
kernel, resulting in a denial of service or potentially escalating
privileges on the system (bnc#1151350).

CVE-2019-15505: An out-of-bounds issue had been fixed that could be
caused by crafted USB device traffic (bnc#1147122).

CVE-2017-18595: A double free in allocate_trace_buffer was fixed
(bnc#1149555).

CVE-2019-14835: A buffer overflow flaw was found in the kernel's vhost
functionality that translates virtqueue buffers to IOVs. A privileged
guest user able to pass descriptors with invalid length to the host
could use this flaw to increase their privileges on the host
(bnc#1150112).

CVE-2019-15216: A NULL pointer dereference was fixed that could be
malicious USB device (bnc#1146361).

CVE-2019-9456: An out-of-bounds write in the USB monitor driver has
been fixed. This issue could lead to local escalation of privilege
with System execution privileges needed. (bnc#1150025).

CVE-2019-15926: An out-of-bounds access was fixed in the
drivers/net/wireless/ath/ath6kl module. (bnc#1149527).

CVE-2019-15927: An out-of-bounds access was fixed in the
sound/usb/mixer module (bnc#1149522).

CVE-2019-15219: A NULL pointer dereference was fixed that could be
abused by a malicious USB device (bnc#1146524).

CVE-2019-15220: A use-after-free issue was fixed that could be caused
by a malicious USB device (bnc#1146526).

CVE-2019-15221: A NULL pointer dereference was fixed that could be
caused by a malicious USB device (bnc#1146529).

CVE-2019-14814: A heap-based buffer overflow was fixed in the marvell
wifi chip driver. That issue allowed local users to cause a denial of
service (system crash) or possibly execute arbitrary code
(bnc#1146512).

CVE-2019-14815: A missing length check while parsing WMM IEs was fixed
(bsc#1146512, bsc#1146514, bsc#1146516).

CVE-2019-14816: A heap-based buffer overflow in the marvell wifi chip
driver was fixed. Local users would have abused this issue to cause a
denial of service (system crash) or possibly execute arbitrary code
(bnc#1146516).

CVE-2017-18509: An issue in net/ipv6 as fixed. By setting a specific
socket option, an attacker could control a pointer in kernel land and
cause an inet_csk_listen_stop general protection fault, or potentially
execute arbitrary code under certain circumstances. The issue can be
triggered as root (e.g., inside a default LXC container or with the
CAP_NET_ADMIN capability) or after namespace unsharing. (bnc#1145477)

CVE-2019-9506: The Bluetooth BR/EDR specification used to permit
sufficiently low encryption key length and did not prevent an attacker
from influencing the key length negotiation. This allowed practical
brute-force attacks (aka 'KNOB') that could decrypt traffic and inject
arbitrary ciphertext without the victim noticing (bnc#1137865).

CVE-2019-15098: A NULL pointer dereference in drivers/net/wireless/ath
was fixed (bnc#1146378).

CVE-2019-15290: A NULL pointer dereference in
ath6kl_usb_alloc_urb_from_pipe was fixed (bsc#1146378).

CVE-2019-15212: A double-free issue was fixed in drivers/usb driver
(bnc#1146391).

CVE-2016-10906: A use-after-free issue was fixed in
drivers/net/ethernet/arc (bnc#1146584).

malicious USB device was fixed in the drivers/media/usb/zr364xx driver
(bnc#1146519).

CVE-2019-15218: A NULL pointer dereference caused by a malicious USB
device was fixed in the drivers/media/usb/siano driver (bnc#1146413).

CVE-2019-15215: A use-after-free issue caused by a malicious USB
device was fixed in the drivers/media/usb/cpia2 driver (bnc#1146425).

CVE-2018-20976: A use-after-free issue was fixed in the fs/xfs driver
(bnc#1146285).

CVE-2017-18551: An out-of-bounds write was fixed in the drivers/i2c
driver (bnc#1146163).

CVE-2019-10207: Add checks for missing tty operations to prevent
unprivileged user to execute 0x0 address (bsc#1142857 bsc#1123959)

CVE-2019-15118: ALSA: usb-audio: Fix a stack-based buffer overflow bug

"Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.

CVE-2016-10905

A race condition was discovered in the GFS2 file-system
implementation, which could lead to a use-after-free. On a system
using GFS2, a local attacker could use this for denial of service
(memory corruption or crash) or possibly for privilege escalation.

CVE-2018-20976

It was discovered that the XFS file-system implementation did not
correctly handle some mount failure conditions, which could lead to a
use-after-free. The security impact of this is unclear.

CVE-2018-21008

It was discovered that the rsi wifi driver did not correctly handle
some failure conditions, which could lead to a use-after- free. The
security impact of this is unclear.

CVE-2019-0136

It was discovered that the wifi soft-MAC implementation (mac80211) did
not properly authenticate Tunneled Direct Link Setup (TDLS) messages.
A nearby attacker could use this for denial of service (loss of wifi
connectivity).

CVE-2019-9506

Daniele Antonioli, Nils Ole Tippenhauer, and Kasper Rasmussen
discovered a weakness in the Bluetooth pairing protocols, dubbed the
'KNOB attack'. An attacker that is nearby during pairing could use
this to weaken the encryption used between the paired devices, and
then to eavesdrop on and/or spoof communication between them.

This update mitigates the attack by requiring a minimum
encryption key length of 56 bits.

CVE-2019-14814, CVE-2019-14815, CVE-2019-14816

Multiple bugs were discovered in the mwifiex wifi driver, which could
lead to heap buffer overflows. A local user permitted to configure a
device handled by this driver could probably use this for privilege
escalation.

CVE-2019-14821

Matt Delco reported a race condition in KVM's coalesced MMIO facility,
which could lead to out-of-bounds access in the kernel. A local
attacker permitted to access /dev/kvm could use this to cause a denial
of service (memory corruption or crash) or possibly for privilege
escalation.

CVE-2019-14835

Peter Pi of Tencent Blade Team discovered a missing bounds check in
vhost_net, the network back-end driver for KVM hosts, leading to a
buffer overflow when the host begins live migration of a VM. An
attacker in control of a VM could use this to cause a denial of
service (memory corruption or crash) or possibly for privilege
escalation on the host.

CVE-2019-15117

Hui Peng and Mathias Payer reported a missing bounds check in the
usb-audio driver's descriptor parsing code, leading to a buffer
over-read. An attacker able to add USB devices could possibly use this
to cause a denial of service (crash).

CVE-2019-15118

Hui Peng and Mathias Payer reported unbounded recursion in the
usb-audio driver's descriptor parsing code, leading to a stack
overflow. An attacker able to add USB devices could use this to cause
a denial of service (memory corruption or crash) or possibly for
privilege escalation.

CVE-2019-15211

The syzkaller tool found a bug in the radio-raremono driver that could
lead to a use-after-free. An attacker able to add and remove USB
devices could use this to cause a denial of service (memory corruption
or crash) or possibly for privilege escalation.

CVE-2019-15212

The syzkaller tool found that the rio500 driver does not work
correctly if more than one device is bound to it. An attacker able to
add USB devices could use this to cause a denial of service (memory
corruption or crash) or possibly for privilege escalation.

CVE-2019-15215

The syzkaller tool found a bug in the cpia2_usb driver that leads to a
use-after-free. An attacker able to add and remove USB devices could
use this to cause a denial of service (memory corruption or crash) or
possibly for privilege escalation.

CVE-2019-15218

The syzkaller tool found that the smsusb driver did not validate that
USB devices have the expected endpoints, potentially leading to a NULL pointer dereference. An attacker able to add USB devices could use
this to cause a denial of service (BUG/oops).

CVE-2019-15219

The syzkaller tool found that a device initialisation error in the
sisusbvga driver could lead to a NULL pointer dereference. An attacker
able to add USB devices could use this to cause a denial of service
(BUG/oops).

CVE-2019-15220

The syzkaller tool found a race condition in the p54usb driver which
could lead to a use-after-free. An attacker able to add and remove USB
devices could use this to cause a denial of service (memory corruption
or crash) or possibly for privilege escalation.

CVE-2019-15221

The syzkaller tool found that the line6 driver did not validate USB
devices' maximum packet sizes, which could lead to a heap buffer
overrun. An attacker able to add USB devices could use this to cause a
denial of service (memory corruption or crash) or possibly for
privilege escalation.

CVE-2019-15292

The Hulk Robot tool found missing error checks in the Appletalk
protocol implementation, which could lead to a use-after-free. The
security impact of this is unclear.

CVE-2019-15807

Jian Luo reported that the Serial Attached SCSI library (libsas) did
not correctly handle failure to discover devices beyond a SAS
expander. This could lead to a resource leak and crash (BUG). The
security impact of this is unclear.

CVE-2019-15917

The syzkaller tool found a race condition in code supporting
UART-attached Bluetooth adapters, which could lead to a use-
after-free. A local user with access to a pty device or other suitable
tty device could use this to cause a denial of service (memory
corruption or crash) or possibly for privilege escalation.

CVE-2019-15926

It was found that the ath6kl wifi driver did not consistently validate
traffic class numbers in received control packets, leading to
out-of-bounds memory accesses. A nearby attacker on the same wifi
network could use this to cause a denial of service (memory corruption
or crash) or possibly for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.74-1.

We recommend that you upgrade your linux packages.

    issue was discovered in fs/xfs/xfs_super.c in the Linux
    kernel before 4.18. A use after free exists, related to
    xfs_fs_fill_super failure.(CVE-2018-20976)In the Linux
    kernel before 5.1.13, there is a memory leak in
    drivers/scsi/libsas/sas_expander.c when SAS expander
    discovery fails. This will cause a BUG and denial of
    service.(CVE-2019-15807)A vulnerability was found in
    Linux kernel's, versions up to 3.10, implementation of
    overlayfs. An attacker with local access can create a
    denial of service situation via NULL pointer
    dereference in ovl_posix_acl_create function in
    fs/overlayfs/dir.c. This can allow attackers with
    ability to create directories on overlayfs to crash the
    kernel creating a denial of service
    (DOS).(CVE-2019-10140)In the Linux kernel, a certain
    net/ipv4/tcp_output.c change, which was properly
    incorporated into 4.16.12, was incorrectly backported
    to the earlier longterm kernels, introducing a new
    vulnerability that was potentially more severe than the
    issue that was intended to be fixed by backporting.
    Specifically, by adding to a write queue between
    disconnection and re-connection, a local attacker can
    trigger multiple use-after-free conditions. This can
    result in a kernel crash, or potentially in privilege
    escalation.(CVE-2019-15239)check_input_term in
    sound/usb/mixer.c in the Linux kernel through 5.2.9
    mishandles recursion, leading to kernel stack
    exhaustion.(CVE-2019-15118)drivers
    et/wireless/ath/ath10k/usb.c in the Linux kernel
    through 5.2.8 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15099)drivers
    et/wireless/ath/ath6kl/usb.c in the Linux kernel
    through 5.2.9 has a NULL pointer dereference via an
    incomplete address in an endpoint
    descriptor.(CVE-2019-15098)A flaw was found in the
    Linux kernel's Bluetooth implementation of UART. An
    attacker with local access and write permissions to the
    Bluetooth hardware could use this flaw to issue a
    specially crafted ioctl function call and cause the
    system to crash.(CVE-2019-10207)It was found that cephx
    authentication protocol did not verify ceph clients
    correctly and was vulnerable to replay attack. Any
    attacker having access to ceph cluster network who is
    able to sniff packets on network can use this
    vulnerability to authenticate with ceph service and
    perform actions allowed by ceph service. Ceph branches
    master, mimic, luminous and jewel are believed to be
    vulnerable.(CVE-2018-1128)ax25_create in
    net/ax25/af_ax25.c in the AF_AX25 network module in the
    Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-0614e2b73768.(CVE-2019-17052)ieee802154_create in
    net/ieee802154/socket.c in the AF_IEEE802154 network
    module in the Linux kernel through 5.3.2 does not
    enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-e69dbd4619e7.(CVE-2019-17053)atalk_create in
    net/appletalk/ddp.c in the AF_APPLETALK network module
    in the Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-6cc03e8aa36c.(CVE-2019-17054)base_sock_create in
    drivers/isdn/mISDN/socket.c in the AF_ISDN network
    module in the Linux kernel through 5.3.2 does not
    enforce CAP_NET_RAW, which means that unprivileged
    users can create a raw socket, aka
    CID-b91ee4aa2a21.(CVE-2019-17055)llcp_sock_create in
    net fc/llcp_sock.c in the AF_NFC network module in the
    Linux kernel through 5.3.2 does not enforce
    CAP_NET_RAW, which means that unprivileged users can
    create a raw socket, aka
    CID-3a359798b176.(CVE-2019-17056)A flaw was found in
    the Linux kernel's freescale hypervisor manager
    implementation, kernel versions 5.0.x up to, excluding
    5.0.17. A parameter passed to an ioctl was incorrectly
    validated and used in size calculations for the page
    size calculation. An attacker can use this flaw to
    crash the system, corrupt memory, or create other
    adverse security
    affects.(CVE-2019-10142)drivers/media/usb/dvb-usb/techn
    isat-usb2.c in the Linux kernel through 5.2.9 has an
    out-of-bounds read via crafted USB device traffic
    (which may be remote via usbip or
    usbredir).(CVE-2019-15505)An issue was discovered in
    the Linux kernel before 5.0.4. The 9p filesystem did
    not protect i_size_write() properly, which causes an
    i_size_read() infinite loop and denial of service on
    SMP systems.(CVE-2019-16413)An issue was discovered in
    xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux
    kernel through 5.2.9. XFS partially wedges when a chgrp
    fails on account of being out of disk quota.
    xfs_setattr_nonsize is failing to unlock the ILOCK
    after the xfs_qm_vop_chown_reserve call fails. This is
    primarily a local DoS attack vector, but it might
    result as well in remote DoS if the XFS filesystem is
    exported for instance via NFS.(CVE-2019-15538)A buffer
    overflow flaw was found, in versions from 2.6.34 to
    5.2.x, in the way Linux kernel's vhost functionality
    that translates virtqueue buffers to IOVs, logged the
    buffer descriptors during migration. A privileged guest
    user able to pass descriptors with invalid length to
    the host when migration is underway, could use this
    flaw to increase their privileges on the
    host.(CVE-2019-14835)An out-of-bounds access issue was
    found in the Linux kernel, all versions through 5.3, in
    the way Linux kernel's KVM hypervisor implements the
    Coalesced MMIO write operation. It operates on an MMIO
    ring buffer 'struct kvm_coalesced_mmio' object, wherein
    write indices 'ring->first' and 'ring->last' value
    could be supplied by a host user-space process. An
    unprivileged host user or process with access to
    '/dev/kvm' device could use this flaw to crash the host
    kernel, resulting in a denial of service or potentially
    escalating privileges on the system.(CVE-2019-14821)An
    information disclosure vulnerability exists when
    certain central processing units (CPU) speculatively
    access memory, aka 'Windows Kernel Information
    Disclosure Vulnerability'.
    (CVE-2019-1125)drivers/scsi/qla2xxx/qla_os.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue
    return value, leading to a NULL pointer
    dereference.(CVE-2019-16233)An issue was discovered in
    the Linux kernel before 5.0.11. fm10k_init_module in
    drivers et/ethernet/intel/fm10k/fm10k_main.c has a NULL
    pointer dereference because there is no -ENOMEM upon an
    alloc_workqueue failure.(CVE-2019-15924)An issue was
    discovered in the Linux kernel before 5.2.1. There is a
    use-after-free caused by a malicious USB device in the
    drivers et/wireless/intersil/p54/p54usb.c
    driver.(CVE-2019-15220 )In the Linux kernel before
    5.1.7, a device can be tracked by an attacker using the
    IP ID values the kernel produces for connection-less
    protocols (e.g., UDP and ICMP). When such traffic is
    sent to multiple destination IP addresses, it is
    possible to obtain hash collisions (of indices to the
    counter array) and thereby obtain the hashing key (via
    enumeration). An attack may be conducted by hosting a
    crafted web page that uses WebRTC or gQUIC to force UDP
    traffic to attacker-controlled IP
    addresses.(CVE-2019-10638)There is heap-based buffer
    overflow in Linux kernel, all versions up to, excluding
    5.3, in the marvell wifi chip driver in Linux kernel,
    that allows local users to cause a denial of
    service(system crash) or possibly execute arbitrary
    code.( CVE-2019-14814)** RESERVED ** This candidate has
    been reserved by an organization or individual that
    will use it when announcing a new security problem.
    When the candidate has been publicized, the details for
    this candidate will be provided.( CVE-2019-14815)There
    is heap-based buffer overflow in kernel, all versions
    up to, excluding 5.3, in the marvell wifi chip driver
    in Linux kernel, that allows local users to cause a
    denial of service(system crash) or possibly execute
    arbitrary code.( CVE-2019-14816)A flaw was found in the
    way Linux kernel KVM hypervisor emulated instructions
    such as sgdt/sidt/fxsave/fxrstor. It did not check
    current privilege(CPL) level while emulating
    unprivileged instructions. An unprivileged guest
    user/process could use this flaw to potentially
    escalate privileges inside guest.(CVE-2018-10853)A NULL
    pointer dereference was found in the net/rds/rdma.c
    __rds_rdma_map() function in the Linux kernel before
    4.14.7 allowing local attackers to cause a system panic
    and a denial-of-service, related to RDS_GET_MR and
    RDS_GET_MR_FOR_DEST.(CVE-2018-7492)An issue was
    discovered in the Linux kernel before 4.20.15. The
    nfc_llcp_build_tlv function in net fc/llcp_commands.c
    may return NULL. If the caller does not check for this,
    it will trigger a NULL pointer dereference. This will
    cause denial of service. This affects nfc_llcp_build_gb
    in netfc/llcp_core.c.(CVE-2019-12818)An issue was
    discovered in the Linux kernel before 5.1.8. There is a
    NULL pointer dereference caused by a malicious USB

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):Heap-based buffer overflow in the udf_load_logicalvol function in fs/udf/super.c in the Linux kernel before 3.4.5 allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via a crafted UDF filesystem.(CVE-2012-3400)The mmc_ioctl_cdrom_read_data function in drivers/cdrom/cdrom.c in the Linux kernel through 3.10 allows local users to obtain sensitive information from kernel memory via a read operation on a malfunctioning CD-ROM drive.(CVE-2013-2164)The sctp_sf_do_5_2_4_dupcook function in net/sctp/sm_statefuns.c in the SCTP implementation in the Linux kernel before 3.8.5 does not properly handle associations during the processing of a duplicate COOKIE ECHO chunk, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via crafted SCTP traffic.(CVE-2013-2206)The (1) get_user and (2) put_user API functions in the Linux kernel before 3.5.5 on the v6k and v7 ARM platforms do not validate certain addresses, which allows attackers to read or modify the contents of arbitrary kernel memory locations via a crafted application, as exploited in the wild against Android devices in October and November 2013.(CVE-2013-6282)An issue was discovered in the Linux kernel before 4.20. There is a race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/libsas/sas_expander.c, leading to a use-after-free.(CVE-2018-20836)The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the Linux kernel before 5.0.8 has multiple race conditions.(CVE-2019-11486)The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.(CVE-2019-11487)The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A n issue was discovered in the Linux kernel before 5.0.7. A NULL pointer dereference can occur when megasas_create_frame_pool() fails in megasas_alloc_cmds() in drivers/scsi/megaraid/megaraid_sas_base.c. This causes a Denial of Service, related to a use-after-free.(CVE-2019-11810)An issue was discovered in the Linux kernel before 5.0.4. There is a use-after-free upon attempted read access to /proc/ioports after the ipmi_si module is removed, related to drivers/char/ipmi/ipmi_si_intf.c, drivers/char/ipmi/ipmi_si_mem_io.c, and drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A flaw was found in the Linux kernel

    mmc_ioctl_cdrom_read_data function in
    drivers/cdrom/cdrom.c in the Linux kernel through 3.10
    allows local users to obtain sensitive information from
    kernel memory via a read operation on a malfunctioning
    CD-ROM drive.(CVE-2013-2164)The
    sctp_sf_do_5_2_4_dupcook function in
    net/sctp/sm_statefuns.c in the SCTP implementation in
    the Linux kernel before 3.8.5 does not properly handle
    associations during the processing of a duplicate
    COOKIE ECHO chunk, which allows remote attackers to
    cause a denial of service (NULL pointer dereference and
    system crash) or possibly have unspecified other impact
    via crafted SCTP traffic.(CVE-2013-2206)The (1)
    get_user and (2) put_user API functions in the Linux
    kernel before 3.5.5 on the v6k and v7 ARM platforms do
    not validate certain addresses, which allows attackers
    to read or modify the contents of arbitrary kernel
    memory locations via a crafted application, as
    exploited in the wild against Android devices in
    October and November 2013.(CVE-2013-6282)An issue was
    discovered in the Linux kernel before 4.20. There is a
    race condition in smp_task_timedout() and
    smp_task_done() in drivers/scsi/libsas/sas_expander.c,
    leading to a use-after-free.(CVE-2018-20836)The Siemens
    R3964 line discipline driver in drivers/tty/n_r3964.c
    in the Linux kernel before 5.0.8 has multiple race
    conditions.(CVE-2019-11486)The Linux kernel before
    5.1-rc5 allows page->_refcount reference count
    overflow, with resultant use-after-free issues, if
    about 140 GiB of RAM exists. This is related to
    fs/fuse/dev.c, fs/pipe.c, fs/splice.c,
    include/linux/mm.h, include/linux/pipe_fs_i.h,
    kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It
    can occur with FUSE requests.(CVE-2019-11487)The
    coredump implementation in the Linux kernel before
    5.0.10 does not use locking or other mechanisms to
    prevent vma layout or vma flags changes while it runs,
    which allows local users to obtain sensitive
    information, cause a denial of service, or possibly
    have unspecified other impact by triggering a race
    condition with mmget_not_zero or get_task_mm calls.
    This is related to fs/userfaultfd.c, mm/mmap.c,
    fs/proc/task_mmu.c, and
    drivers/infiniband/core/uverbs_main.c.(CVE-2019-11599)A
    n issue was discovered in the Linux kernel before
    5.0.7. A NULL pointer dereference can occur when
    megasas_create_frame_pool() fails in
    megasas_alloc_cmds() in
    drivers/scsi/megaraid/megaraid_sas_base.c. This causes
    a Denial of Service, related to a
    use-after-free.(CVE-2019-11810)An issue was discovered
    in the Linux kernel before 5.0.4. There is a
    use-after-free upon attempted read access to
    /proc/ioports after the ipmi_si module is removed,
    related to drivers/char/ipmi/ipmi_si_intf.c,
    drivers/char/ipmi/ipmi_si_mem_io.c, and
    drivers/char/ipmi/ipmi_si_port_io.c.(CVE-2019-11811)A
    flaw was found in the Linux kernel's handle_rx()
    function in the [vhost_net] driver. A malicious virtual
    guest, under specific conditions, can trigger an
    out-of-bounds write in a kmalloc-8 slab on a virtual
    host which may lead to a kernel memory corruption and a
    system panic. Due to the nature of the flaw, privilege
    escalation cannot be fully ruled out. Versions from
    v4.16 and newer are vulnerable.(CVE-2018-16880)An issue
    was discovered in rds_tcp_kill_sock in net/rds/tcp.c in
    the Linux kernel before 5.0.8. There is a race
    condition leading to a use-after-free, related to net
    namespace cleanup.(CVE-2019-11815)A flaw was found in
    the Linux kernel in the function
    hid_debug_events_read() in drivers/hid/hid-debug.c file
    which may enter an infinite loop with certain
    parameters passed from a userspace. A local privileged
    user ('root') can cause a system lock up and a denial
    of service. Versions from v4.18 and newer are
    vulnerable.(CVE-2019-3819)A flaw was found in the Linux
    kernel's vfio interface implementation that permits
    violation of the user's locked memory limit. If a
    device is bound to a vfio driver, such as vfio-pci, and
    the local attacker is administratively granted
    ownership of the device, it may cause a system memory
    exhaustion and thus a denial of service (DoS). Versions
    3.10, 4.14 and 4.18 are vulnerable.(CVE-2019-3882)An
    infinite loop issue was found in the vhost_net kernel
    module in Linux Kernel up to and including v5.1-rc6,
    while handling incoming packets in handle_rx(). It
    could occur if one end sends packets faster than the
    other end can process them. A guest user, maybe remote
    one, could use this flaw to stall the vhost_net kernel
    thread, resulting in a DoS scenario.(CVE-2019-3900)In
    the Linux Kernel before versions 4.20.8 and 4.19.21 a
    use-after-free error in the 'sctp_sendmsg()' function
    (net/sctp/socket.c) when handling SCTP_SENDALL flag can
    be exploited to corrupt memory.(CVE-2019-8956)A flaw
    was found in the Linux kernel's implementation of ext4
    extent management. The kernel doesn't correctly
    initialize memory regions in the extent tree block
    which may be exported to a local user to obtain
    sensitive information by reading empty/uninitialized
    data from the filesystem.(CVE-2019-11833)An issue was
    discovered in drm_load_edid_firmware in
    drivers/gpu/drm/drm_edid_load.c in the Linux kernel
    through 5.1.5. There is an unchecked kstrdup of fwstr,
    which might allow an attacker to cause a denial of
    service (NULL pointer dereference and system crash).
    NOTE: The vendor disputes this issues as not being a
    vulnerability because kstrdup() returning NULL is
    handled sufficiently and there is no chance for a NULL
    pointer dereference.(CVE-2019-12382)An issue was
    discovered in the efi subsystem in the Linux kernel
    through 5.1.5. phys_efi_set_virtual_address_map in
    arch/x86/platform/efi/efi.c and efi_call_phys_prolog in
    arch/x86/platform/efi/efi_64.c mishandle memory
    allocation failures. NOTE: This id is disputed as not
    being an issue because ?All the code touched by the
    referenced commit runs only at boot, before any user
    processes are started. Therefore, there is no
    possibility for an unprivileged user to control
    it.(CVE-2019-12380)An issue was discovered in the Linux
    kernel before 5.2.3. An out of bounds access exists in
    the function hclge_tm_schd_mode_vnet_base_cfg in the
    file drivers
    et/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c.(CVE-2019-
    15925)An issue was discovered in
    dlpar_parse_cc_property in
    arch/powerpc/platforms/pseries/dlpar.c in the Linux
    kernel through 5.1.6. There is an unchecked kstrdup of
    prop-i1/4zname, which might allow an attacker to cause a
    denial of service (NULL pointer dereference and system
    crash).(CVE-2019-12614)An issue was discovered in
    net/ipv4/sysctl_net_ipv4.c in the Linux kernel before
    5.0.11. There is a net/ipv4/tcp_input.c signed integer
    overflow in tcp_ack_update_rtt() when userspace writes
    a very large integer to
    /proc/syset/ipv4/tcp_min_rtt_wlen, leading to a denial
    of service or possibly unspecified other impact, aka
    CID-19fad20d15a6.(CVE-2019-18805)A flaw was found in
    the way PTRACE_TRACEME functionality was handled in the
    Linux kernel. The kernel's implementation of ptrace can
    inadvertently grant elevated permissions to an attacker
    who can then abuse the relationship between the tracer
    and the process being traced. This flaw could allow a
    local, unprivileged user to increase their privileges
    on the system or cause a denial of
    service.(CVE-2019-13272)An issue was discovered in
    ip6_ra_control in net/ipv6/ipv6_sockglue.c in the Linux
    kernel through 5.1.5. There is an unchecked kmalloc of
    new_ra, which might allow an attacker to cause a denial
    of service (NULL pointer dereference and system crash).
    NOTE: This has been disputed as not an
    issue.(CVE-2019-12378)An issue was discovered in
    ip_ra_control in net/ipv4/ip_sockglue.c in the Linux
    kernel through 5.1.5. There is an unchecked kmalloc of
    new_ra, which might allow an attacker to cause a denial
    of service (NULL pointer dereference and system crash).
    NOTE: this is disputed because new_ra is never used if
    it is NULL.(CVE-2019-12381)An issue was discovered in
    sunxi_divs_clk_setup in drivers/clk/sunxi/clk-sunxi.c
    in the Linux kernel through 5.1.5. There is an
    unchecked kstrndup of derived_name, which might allow
    an attacker to cause a denial of service (NULL pointer
    dereference and system crash). NOTE: This id is
    disputed as not being an issue because 'The memory
    allocation that was not checked is part of a code that
    only runs at boot time, before user processes are
    started. Therefore, there is no possibility for an
    unprivileged user to control it, and no denial of
    service.'.(CVE-2019-12455)An issue was discovered in
    the MPT3COMMAND case in _ctl_ioctl_main in
    drivers/scsi/mpt3sas/mpt3sas_ctl.c in the Linux kernel
    through 5.1.5. It allows local users to cause a denial
    of service or possibly have unspecified other impact by
    changing the value of ioc_number between two kernel
    reads of that value, aka a ''double fetch''
    vulnerability. NOTE: a third party reports that this is
    unexploitable because the doubly fetched value is not
    used.(CVE-2019-12456)An issue was discovered in
    get_vdev_port_node_info in arch/sparc/kernel/mdesc.c in
    the Linux kernel through 5.1.6. There is an unchecked
    kstrdup_const of node_info-i1/4zvdev_port.name, which
    might allow an attacker to cause a denial of service
    (NULL pointer dereference and system
    crash).(CVE-2019-12615)In parse_hid_report_descriptor
    in drivers/input/tablet/gtco.c in the Linux kernel
    through 5.2.1, a malicious USB device can send an HID
    report that triggers an out-of-bounds write during
    generation of debugging messages.(CVE-2019-13631)A
    vulnerability was found in the Linux kernelaEURtms floppy
    disk driver implementation. A local attacker with
    access to the floppy device could call set_geometry in
    drivers/block/floppy.c, which does not validate the
    sect and head fields, causing an integer overflow and
    out-of-bounds read. This flaw may crash the system or
    allow an attacker to gather information causing
    subsequent successful
    attacks.(CVE-2019-14283)check_input_term in
    sound/usb/mixer.c in the Linux kernel through 5.2.9
    mishandles recursion, leading to kernel stack
    exhaustion.(CVE-2019-15118)An issue was discovered in
    the Linux kernel before 5.2.6. There is a
    use-after-free caused by a malicious USB device in the
    drivers/media/v4l2-core/v4l2-dev.c driver because
    drivers/media/radio/radio-raremono.c does not properly
    allocate memory.(CVE-2019-15211)An issue was discovered
    in the Linux kernel before 5.0.10. There is a
    use-after-free in the sound subsystem because card
    disconnection causes certain data structures to be
    deleted too early. This is related to sound/core/init.c
    and sound/core/info.c.(CVE-2019-15214)An issue was
    discovered in the Linux kernel before 5.1.8. There is a
    NULL pointer dereference caused by a malicious USB
    device in the drivers/media/usb/siano/smsusb.c
    driver.(CVE-2019-15218)An issue was discovered in the
    Linux kernel before 5.1.8. There is a NULL pointer
    dereference caused by a malicious USB device in the
    drivers/usb/misc/sisusbvga/sisusb.c
    driver.(CVE-2019-15219)An issue was discovered in the
    Linux kernel before 5.2.1. There is a use-after-free
    caused by a malicious USB device in the
    driverset/wireless/intersil/p54/p54usb.c
    driver.(CVE-2019-15220)An issue was discovered in the
    Linux kernel before 5.1.17. There is a NULL pointer
    dereference caused by a malicious USB device in the
    sound/usb/line6/pcm.c driver.(CVE-2019-15221)An issue
    was discovered in the Linux kernel before 5.0.9. There
    is a use-after-free in atalk_proc_exit, related to
    net/appletalk/atalk_proc.c, net/appletalk/ddp.c, and
    net/appletalk/sysctl_net_atalk.c.(CVE-2019-15292)An
    issue was discovered in xfs_setattr_nonsize in
    fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9.
    XFS partially wedges when a chgrp fails on account of
    being out of disk quota. xfs_setattr_nonsize is failing
    to unlock the ILOCK after the xfs_qm_vop_chown_reserve
    call fails. This is primarily a local DoS attack
    vector, but it might result as well in remote DoS if
    the XFS filesystem is exported for instance via
    NFS.(CVE-2019-15538)An issue was discovered in the
    Linux kernel before 5.0.19. There is an out-of-bounds
    array access in __xfrm_policy_unlink, which will cause
    denial of service, because verify_newpolicy_info in
    net/xfrm/xfrm_user.c mishandles directory
    validation.(CVE-2019-15666)In the Linux kernel before
    5.1.13, there is a memory leak in
    drivers/scsi/libsas/sas_expander.c when SAS expander
    discovery fails. This will cause a BUG and denial of
    service.(CVE-2019-15807)An issue was discovered in the
    Linux kernel before 5.0.5. There is a use-after-free
    issue when hci_uart_register_dev() fails in
    hci_uart_set_proto() in
    drivers/bluetooth/hci_ldisc.c.(CVE-2019-15917)An issue
    was discovered in the Linux kernel before 5.0.10.
    SMB2_write in fs/cifs/smb2pdu.c has a
    use-after-free.(CVE-2019-15919)An issue was discovered
    in the Linux kernel before 5.0.10. SMB2_read in
    fs/cifs/smb2pdu.c has a use-after-free. NOTE: this was
    not fixed correctly in 5.0.10 see the 5.0.11 ChangeLog,
    which documents a memory leak.(CVE-2019-15920)An issue
    was discovered in the Linux kernel before 5.0.4. The 9p
    filesystem did not protect i_size_write() properly,
    which causes an i_size_read() infinite loop and denial
    of service on SMP systems.(CVE-2019-16413)An issue was
    discovered in can_can_gw_rcv in net/can/gw.c in the
    Linux kernel through 4.19.13. The CAN frame
    modification rules allow bitwise logical operations
    that can be also applied to the can_dlc field. Because
    of a missing check, the CAN drivers may write arbitrary
    content beyond the data registers in the CAN
    controller's I/O memory when processing can-gw
    manipulated outgoing frames. This is related to
    cgw_csum_xor_rel. An unprivileged user can trigger a
    system crash (general protection
    fault).(CVE-2019-3701)A flaw was found in the Linux
    kernel's Marvell wifi chip driver. A heap overflow in
    mwifiex_update_bss_desc_with_ie function in
    marvell/mwifiex/scan.c allows remote attackers to cause
    a denial of service(system crash) or execute arbitrary
    code.(CVE-2019-3846)A new software page cache side
    channel attack scenario was discovered in operating
    systems that implement the very common 'page cache'
    caching mechanism. A malicious user/process could use
    'in memory' page-cache knowledge to infer access
    timings to shared memory and gain knowledge which can
    be used to reduce effectiveness of cryptographic
    strength by monitoring algorithmic behavior, infer
    access patterns of memory to determine code paths
    taken, and exfiltrate data to a blinded attacker
    through page-granularity access times as a
    side-channel.(CVE-2019-5489)In the Android kernel in
    the video driver there is a kernel pointer leak due to
    a WARN_ON statement. This could lead to local
    information disclosure with System execution privileges
    needed. User interaction is not needed for
    exploitation.(CVE-2019-9455)A vulnerability was found
    in the arch/x86/lib/insn-eval.c function in the Linux
    kernel. An attacker could corrupt the memory due to a
    flaw in use-after-free access to an LDT entry caused by
    a race condition between modify_ldt() and a #BR
    exception for an MPX bounds violation.(CVE-2019-13233)

    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities : - In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.(CVE-2018-7191) - A memory leak in the crypto_report() function in crypto/crypto_user_base.c in the Linux kernel through 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering crypto_report_alg() failures, aka CID-ffdde5932042.(CVE-2019-19062) - An issue was discovered in net/ipv4/sysctl_net_ipv4.c in the Linux kernel before 5.0.11. There is a net/ipv4/tcp_input.c signed integer overflow in tcp_ack_update_rtt() when userspace writes a very large integer to /proc/sys/net/ipv4/tcp_min_rtt_wlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6.(CVE-2019-18805) - In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a.(CVE-2019-16994) - An issue was discovered in the Linux kernel before 5.0.6. There is a memory leak issue when idr_alloc() fails in genl_register_family() in net/netlink/genetlink.c.(CVE-2019-15921) - In the Linux kernel before 5.1.13, there is a memory leak in drivers/scsi/libsas/sas_expander.c when SAS expander discovery fails. This will cause a BUG and denial of service.(CVE-2019-15807) - An issue was discovered in xfs_setattr_nonsize in fs/xfs/xfs_iops.c in the Linux kernel through 5.2.9. XFS partially wedges when a chgrp fails on account of being out of disk quota. xfs_setattr_nonsize is failing to unlock the ILOCK after the xfs_qm_vop_chown_reserve call fails. This is primarily a local DoS attack vector, but it might result as well in remote DoS if the XFS filesystem is exported for instance via NFS.(CVE-2019-15538) - An out-of-bounds access issue was found in the Linux kernel, all versions through 5.3, in the way Linux kernel

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):The yam_ioctl function in drivers et/hamradio/yam.c in the Linux kernel before 3.12.8 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel memory by leveraging the CAP_NET_ADMIN capability for an SIOCYAMGCFG ioctl call.(CVE-2014-1446)The VFS subsystem in the Linux kernel 3.x provides an incomplete set of requirements for setattr operations that underspecifies removing extended privilege attributes, which allows local users to cause a denial of service (capability stripping) via a failed invocation of a system call, as demonstrated by using chown to remove a capability from the ping or Wireshark dumpcap program.(CVE-2015-1350)A certain backport in the TCP Fast Open implementation for the Linux kernel before 3.18 does not properly maintain a count value, which allow local users to cause a denial of service (system crash) via the Fast Open feature, as demonstrated by visiting the chrome://flags/#enable-tcp-fast-open URL when using certain 3.10.x through 3.16.x kernel builds, including longterm-maintenance releases and ckt (aka Canonical Kernel Team) builds.(CVE-2015-3332)The hub_activate function in drivers/usb/core/hub.c in the Linux kernel before 4.3.5 does not properly maintain a hub-interface data structure, which allows physically proximate attackers to cause a denial of service (invalid memory access and system crash) or possibly have unspecified other impact by unplugging a USB hub device.(CVE-2015-8816)In the Linux kernel before 4.1.4, a buffer overflow occurs when checking userspace params in drivers/media/dvb-frontends/cx24116.c. The maximum size for a DiSEqC command is 6, according to the userspace API. However, the code allows larger values such as 23.(CVE-2015-9289)The create_fixed_stream_quirk function in sound/usb/quirks.c in the snd-usb-audio driver in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference or double free, and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2184)The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2185)The powermate_probe function in drivers/input/misc/powermate.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2186)The gtco_probe function in drivers/input/tablet/gtco.c in the Linux kernel through 4.5.2 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-2187)Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor.(CVE-2016-2384)The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint.(CVE-2016-2782)The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor.(CVE-2016-3138)The wacom_probe function in drivers/input/tablet/wacom_sys.c in the Linux kernel before 3.17 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3139)The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor.(CVE-2016-3140)The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel before 4.5.1 allows physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface.(CVE-2016-3689)The snd_timer_user_params function in sound/core/timer.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface.(CVE-2016-4569)sound/core/timer.c in the Linux kernel through 4.6 does not initialize certain r1 data structures, which allows local users to obtain sensitive information from kernel stack memory via crafted use of the ALSA timer interface, related to the (1) snd_timer_user_ccallback and (2) snd_timer_user_tinterrupt functions.(CVE-2016-4578)The x25_negotiate_facilities function in net/x25/x25_facilities.c in the Linux kernel before 4.5.5 does not properly initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory via an X.25 Call Request.(CVE-2016-4580)The arcmsr_iop_message_xfer function in drivers/scsi/arcmsr/arcmsr_hba.c in the Linux kernel through 4.8.2 does not restrict a certain length field, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) via an ARCMSR_MESSAGE_WRITE_WQBUFFER control code.(CVE-2016-7425)The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack. Linux Kernel version 4.11.5 is affected.(CVE-2017-1000379)In android for MSM, Firefox OS for MSM, QRD Android, with all Android releases from CAF using the Linux kernel, a buffer overread is observed in nl80211_set_station when user space application sends attribute NL80211_ATTR_LOCAL_MESH_POWER_MODE with data of size less than 4 bytes(CVE-2017-11089)An elevation of privilege vulnerability in the kernel sound timer. Product: Android. Versions: Android kernel. Android ID A-37240993.(CVE-2017-13167)In ashmem_ioctl of ashmem.c, there is an out-of-bounds write due to insufficient locking when accessing asma. This could lead to a local elevation of privilege enabling code execution as a privileged process with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-66954097.(CVE-2017-13216)A information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions: Android kernel. Android ID: A-70526974.(CVE-2017-13305)An integer overflow in the qla2x00_sysfs_write_optrom_ctl function in drivers/scsi/qla2xxx/qla_attr.c in the Linux kernel through 4.12.10 allows local users to cause a denial of service (memory corruption and system crash) by leveraging root access.(CVE-2017-14051)The Serial Attached SCSI (SAS) implementation in the Linux kernel through 4.15.9 mishandles a mutex within libsas, which allows local users to cause a denial of service (deadlock) by triggering certain error-handling code.(CVE-2017-18232)An issue was discovered in net/ipv6/ip6mr.c in the Linux kernel before 4.11. By setting a specific socket option, an attacker can control a pointer in kernel land and cause an inet_csk_listen_stop general protection fault, or potentially execute arbitrary code under certain circumstances. The issue can be triggered as root (e.g., inside a default LXC container or with the CAP_NET_ADMIN capability) or after namespace unsharing. This occurs because sk_type and protocol are not checked in the appropriate part of the ip6_mroute_* functions. NOTE: this affects Linux distributions that use 4.9.x longterm kernels before 4.9.187.(CVE-2017-18509)An issue was discovered in drivers/i2c/i2c-core-smbus.c in the Linux kernel before 4.14.15. There is an out of bounds write in the function i2c_smbus_xfer_emulated.(CVE-2017-18551)An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.(CVE-2017-18595)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)The kernel_wait4 function in kernel/exit.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service by triggering an attempted use of the -INT_MIN value.(CVE-2018-10087)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)The xfs_dinode_verify function in fs/xfs/libxfs/xfs_inode_buf.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_ilock_attr_map_shared invalid pointer dereference) via a crafted xfs image.(CVE-2018-10322)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)Linux kernel is vulnerable to a stack-out-of-bounds write in the ext4 filesystem code when mounting and writing to a crafted ext4 image in ext4_update_inline_data(). An attacker could use this to cause a system crash and a denial of service.(CVE-2018-10880)An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls.(CVE-2018-12896)An issue was discovered in the proc_pid_stack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents.(CVE-2018-17972)An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940 and CVE-2018-16658.(CVE-2018-18710 )An issue was discovered in the Linux kernel before 4.18.11.

    NASL idEULEROS_SA-2019-2274.NASL
    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc.Security Fix(es):Systems with microprocessors utilizing speculative execution and indirect branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis of the data cache.(CVE-2017-5754)The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access.(CVE-2017-5897)The vmw_surface_define_ioctl function in drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux kernel through 4.10.5 does not check for a zero value of certain levels data, which allows local users to cause a denial of service (ZERO_SIZE_PTR dereference, and GPF and possibly panic) via a crafted ioctl call for a /dev/dri/renderD* device.(CVE-2017-7261)The KEYS subsystem in the Linux kernel before 4.10.13 allows local users to cause a denial of service (memory consumption) via a series of KEY_REQKEY_DEFL_THREAD_KEYRING keyctl_set_reqkey_keyring calls.(CVE-2017-7472)A flaw was found in the Linux kernel before version 4.12 in the way the KVM module processed the trap flag(TF) bit in EFLAGS during emulation of the syscall instruction, which leads to a debug exception(#DB) being raised in the guest stack. A user/process inside a guest could use this flaw to potentially escalate their privileges inside the guest. Linux guests are not affected by this.(CVE-2017-7518)The kill_something_info function in kernel/signal.c in the Linux kernel before 4.13, when an unspecified architecture and compiler is used, might allow local users to cause a denial of service via an INT_MIN argument.(CVE-2018-10124)The xfs_bmap_extents_to_btree function in fs/xfs/libxfs/xfs_bmap.c in the Linux kernel through 4.16.3 allows local users to cause a denial of service (xfs_bmapi_write NULL pointer dereference) via a crafted xfs image.(CVE-2018-10323)The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setup_ntlmv2_rsp() that allows an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation response is mishandled during session recovery.(CVE-2018-1066)The do_get_mempolicy function in mm/mempolicy.c in the Linux kernel before 4.12.9 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted system calls.(CVE-2018-10675)An issue was discovered in fs/xfs/libxfs/xfs_attr_leaf.c in the Linux kernel through 4.17.3. An OOPS may occur for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp.(CVE-2018-13094)An issue was discovered in fs/xfs/xfs_super.c in the Linux kernel before 4.18. A use after free exists, related to xfs_fs_fill_super failure.(CVE-2018-20976)Systems with microprocessors utilizing speculative execution and branch prediction may allow unauthorized disclosure of information to an attacker with local user access via a speculative buffer overflow and side-channel analysis.(CVE-2018-3693)In the function sbusfb_ioctl_helper() in drivers/video/fbdev/sbuslib.c in the Linux kernel through 4.15, an integer signedness error allows arbitrary information leakage for the FBIOPUTCMAP_SPARC and FBIOGETCMAP_SPARC commands.(CVE-2018-6412)Race condition in the store_int_with_restart() function in arch/x86/kernel/cpu/mcheck/mce.c in the Linux kernel through 4.15.7 allows local users to cause a denial of service (panic) by leveraging root access to write to the check_interval file in a /sys/devices/system/machinecheck/machinecheck directory. NOTE: a third party has indicated that this report is not security relevant.(CVE-2018-7995)In the hidp_process_report in bluetooth, there is an integer overflow. This could lead to an out of bounds write with no additional execution privileges needed. User interaction is not needed for exploitation. Product: Android Versions: Android kernel Android ID: A-65853588 References: Upstream kernel.(CVE-2018-9363)In nfc_llcp_build_sdreq_tlv of llcp_commands.c, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-73083945.(CVE-2018-9518)A vulnerability was found in Linux kernel
