    descriptionAccording to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 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):A flaw named FragmentSmack was found in the way the Linux kernel handled reassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use this flaw to trigger time and calculation expensive fragment reassembly algorithm by sending specially crafted packets which could lead to a CPU saturation and hence a denial of service on the system.(CVE-2018-5391)Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled HID reports with an invalid report descriptor size. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.(CVE-2014-3184)The __get_data_block function in fs/f2fs/data.c in the Linux kernel before 4.11 allows local users to cause a denial of service (integer overflow and loop) via crafted use of the open and fallocate system calls with an FS_IOC_FIEMAP ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations. This allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all network namespaces.(CVE-2017-17450)A denial of service flaw was discovered in the Linux kernel, where a race condition caused a NULL pointer dereference in the RDS socket-creation code. A local attacker could use this flaw to create a situation in which a NULL pointer crashed the kernel.(CVE-2015-7990)An issue was discovered in the Linux kernel before 4.19.9. The USB subsystem mishandles size checks during the reading of an extra descriptor, related to __usb_get_extra_descriptor in drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in the Linux kernel before 4.1.4 mishandles anonymous pages, which allows local users to gain privileges or cause a denial of service (page tainting) via a crafted application that triggers writing to page zero.(CVE-2015-3288)The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel through 4.3.3 attempts to merge distinct setattr operations, which allows local users to bypass intended access restrictions and modify the attributes of arbitrary overlay files via a crafted application.(CVE-2015-8660)A flaw was found in the Linux kernel where a local user with a shell account can abuse the userfaultfd syscall when using hugetlbfs. A missing size check in hugetlb_mcopy_atomic_pte could create an invalid inode variable, leading to a kernel panic.(CVE-2017-15128)An integer overflow flaw was found in the way the lzo1x_decompress_safe() function of the Linux kernel

    calculation expensive fragment reassembly algorithm by
    sending specially crafted packets which could lead to a
    CPU saturation and hence a denial of service on the

    flaws were found in the way the Cherry Cymotion
    keyboard driver, KYE/Genius device drivers, Logitech
    device drivers, Monterey Genius KB29E keyboard driver,
    Petalynx Maxter remote control driver, and Sunplus
    wireless desktop driver handled HID reports with an
    invalid report descriptor size. An attacker with
    physical access to the system could use either of these
    flaws to write data past an allocated memory
    buffer.(CVE-2014-3184)The __get_data_block function in
    fs/f2fs/data.c in the Linux kernel before 4.11 allows
    local users to cause a denial of service (integer
    overflow and loop) via crafted use of the open and
    fallocate system calls with an FS_IOC_FIEMAP
    ioctl.(CVE-2017-18257)netetfilter/xt_osf.c in the Linux
    kernel through 4.14.4 does not require the
    CAP_NET_ADMIN capability for add_callback and
    remove_callback operations. This allows local users to
    bypass intended access restrictions because the
    xt_osf_fingers data structure is shared across all

    flaw was discovered in the Linux kernel, where a race
    condition caused a NULL pointer dereference in the RDS
    socket-creation code. A local attacker could use this
    flaw to create a situation in which a NULL pointer
    crashed the kernel.(CVE-2015-7990)An issue was
    discovered in the Linux kernel before 4.19.9. The USB
    subsystem mishandles size checks during the reading of
    an extra descriptor, related to
    __usb_get_extra_descriptor in
    drivers/usb/core/usb.c.(CVE-2018-20169)mm/memory.c in
    the Linux kernel before 4.1.4 mishandles anonymous
    pages, which allows local users to gain privileges or
    cause a denial of service (page tainting) via a crafted
    application that triggers writing to page
    zero.(CVE-2015-3288)The ovl_setattr function in
    fs/overlayfs/inode.c in the Linux kernel through 4.3.3
    attempts to merge distinct setattr operations, which
    allows local users to bypass intended access
    restrictions and modify the attributes of arbitrary
    overlay files via a crafted
    application.(CVE-2015-8660)A flaw was found in the
    Linux kernel where a local user with a shell account
    can abuse the userfaultfd syscall when using hugetlbfs.
    A missing size check in hugetlb_mcopy_atomic_pte could
    create an invalid inode variable, leading to a kernel
    panic.(CVE-2017-15128)An integer overflow flaw was
    found in the way the lzo1x_decompress_safe() function
    of the Linux kernel's LZO implementation processed
    Literal Runs. A local attacker could, in extremely rare
    cases, use this flaw to crash the system or,
    potentially, escalate their privileges on the
    system.(CVE-2014-4608)It was found that Linux kernel's
    ptrace subsystem did not properly sanitize the
    address-space-control bits when the program-status word
    (PSW) was being set. On IBM S/390 systems, a local,
    unprivileged user could use this flaw to set
    address-space-control bits to the kernel space, and
    thus gain read and write access to kernel
    memory.(CVE-2014-3534)A use-after-free flaw was found
    in the Linux kernel's file system encryption
    implementation. A local user could revoke keyring keys
    being used for ext4, f2fs, or ubifs encryption, causing
    a denial of service on the system.(CVE-2017-7374)The
    usbip_recv_xbuff function in
    drivers/usb/usbip/usbip_common.c in the Linux kernel
    before 4.5.3 allows remote attackers to cause a denial
    of service (out-of-bounds write) or possibly have
    unspecified other impact via a crafted length value in
    a USB/IP packet.(CVE-2016-3955)A flaw was found in the
    patches used to fix the 'dirtycow' vulnerability
    (CVE-2016-5195). An attacker, able to run local code,
    can exploit a race condition in transparent huge pages
    to modify usually read-only huge
    pages.(CVE-2017-1000405)The aio_mount function in
    fs/aio.c in the Linux kernel does not properly restrict
    execute access, which makes it easier for local users
    to bypass intended SELinux W^X policy
    restrictions.(CVE-2016-10044)The Serial Attached SCSI
    (SAS) implementation in the Linux kernel mishandles a
    mutex within libsas. This allows local users to cause a
    denial of service (deadlock) by triggering certain
    error-handling code.(CVE-2017-18232)A use-after-free
    vulnerability was found in tcp_xmit_retransmit_queue
    and other tcp_* functions. This condition could allow
    an attacker to send an incorrect selective
    acknowledgment to existing connections, possibly
    resetting a connection.(CVE-2016-6828)The instruction
    decoder in arch/x86/kvm/emulate.c in the KVM subsystem
    in the Linux kernel before 3.18-rc2 does not properly
    handle invalid instructions, which allows guest OS
    users to cause a denial of service (NULL pointer
    dereference and host OS crash) via a crafted
    application that triggers (1) an improperly fetched
    instruction or (2) an instruction that occupies too
    many bytes. NOTE: this vulnerability exists because of
    an incomplete fix for CVE-2014-8480.(CVE-2014-8481)The
    snd_compress_check_input function in
    sound/core/compress_offload.c in the ALSA subsystem in
    the Linux kernel before 3.17 does not properly check
    for an integer overflow, which allows local users to
    cause a denial of service (insufficient memory
    allocation) or possibly have unspecified other impact
    via a crafted SNDRV_COMPRESS_SET_PARAMS ioctl
    call.(CVE-2014-9904)The resv_map_release function in
    mm/hugetlb.c in the Linux kernel, through 4.15.7,
    allows local users to cause a denial of service (BUG)
    via a crafted application that makes mmap system calls
    and has a large pgoff argument to the remap_file_pages
    system call.(CVE-2018-7740)

"An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* A flaw named FragmentSmack was found in the way the Linux kernel
handled reassembly of fragmented IPv4 and IPv6 packets. A remote
attacker could use this flaw to trigger time and calculation expensive
fragment reassembly algorithm by sending specially crafted packets
which could lead to a CPU saturation and hence a denial of service on
the system. (CVE-2018-5391)

* kernel: out-of-bounds access in the show_timer function in
kernel/time/ posix-timers.c (CVE-2017-18344)

* kernel: Integer overflow in udl_fb_mmap() can allow attackers to
execute code in kernel space (CVE-2018-8781)

* kernel: MIDI driver race condition leads to a double-free
(CVE-2018-10902)

* kernel: Missing check in inode_init_owner() does not clear SGID bit
on non-directories for non-members (CVE-2018-13405)

* kernel: AIO write triggers integer overflow in some protocols
(CVE-2015-8830)

* kernel: Use-after-free in snd_pcm_info function in ALSA subsystem
potentially leads to privilege escalation (CVE-2017-0861)

* kernel: Handling of might_cancel queueing is not properly pretected
against race (CVE-2017-10661)

* kernel: Salsa20 encryption algorithm does not correctly handle
zero-length inputs allowing local attackers to cause denial of service
(CVE-2017-17805)

* kernel: Inifinite loop vulnerability in madvise_willneed() function
allows local denial of service (CVE-2017-18208)

* kernel: fuse-backed file mmap-ed onto process cmdline arguments
causes denial of service (CVE-2018-1120)

* kernel: a NULL pointer dereference in dccp_write_xmit() leads to a
system crash (CVE-2018-1130)

* kernel: drivers/block/loop.c mishandles lo_release serialization
allowing denial of service (CVE-2018-5344)

* kernel: Missing length check of payload in _sctp_make_chunk()
function allows denial of service (CVE-2018-5803)

* kernel: buffer overflow in drivers/net/wireless/ath/wil6210/
wmi.c:wmi_set_ie() may lead to memory corruption (CVE-2018-5848)

* kernel: out-of-bound write in ext4_init_block_bitmap function with a
crafted ext4 image (CVE-2018-10878)

* kernel: Improper validation in bnx2x network card driver can allow
for denial of service attacks via crafted packet (CVE-2018-1000026)

* kernel: Information leak when handling NM entries containing NUL
(CVE-2016-4913)

* kernel: Mishandling mutex within libsas allowing local Denial of
Service (CVE-2017-18232)

* kernel: NULL pointer dereference in ext4_process_freed_data() when
mounting crafted ext4 image (CVE-2018-1092)

* kernel: NULL pointer dereference in ext4_xattr_inode_hash() causes
crash with crafted ext4 image (CVE-2018-1094)

* kernel: vhost: Information disclosure in
vhost/vhost.c:vhost_new_msg() (CVE-2018-1118)

* kernel: Denial of service in resv_map_release function in
mm/hugetlb.c (CVE-2018-7740)

* kernel: Memory leak in the sas_smp_get_phy_events function in
drivers/scsi/ libsas/sas_expander.c (CVE-2018-7757)

* kernel: Invalid pointer dereference in xfs_ilock_attr_map_shared()
when mounting crafted xfs image allowing denial of service
(CVE-2018-10322)

* kernel: use-after-free detected in ext4_xattr_set_entry with a
crafted file (CVE-2018-10879)

* kernel: out-of-bound access in ext4_get_group_info() when mounting
and operating a crafted ext4 image (CVE-2018-10881)

* kernel: stack-out-of-bounds write in jbd2_journal_dirty_metadata
function (CVE-2018-10883)

* kernel: incorrect memory bounds check in drivers/cdrom/cdrom.c
(CVE-2018-10940)

An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux
operating system.

Security Fix(es) :

* A flaw named FragmentSmack was found in the way the Linux kernel
handled reassembly of fragmented IPv4 and IPv6 packets. A remote
attacker could use this flaw to trigger time and calculation expensive
fragment reassembly algorithm by sending specially crafted packets
which could lead to a CPU saturation and hence a denial of service on
the system. (CVE-2018-5391)

* kernel: out-of-bounds access in the show_timer function in
kernel/time/ posix-timers.c (CVE-2017-18344)

* kernel: Integer overflow in udl_fb_mmap() can allow attackers to
execute code in kernel space (CVE-2018-8781)

* kernel: MIDI driver race condition leads to a double-free
(CVE-2018-10902)

* kernel: Missing check in inode_init_owner() does not clear SGID bit
on non-directories for non-members (CVE-2018-13405)

* kernel: AIO write triggers integer overflow in some protocols
(CVE-2015-8830)

* kernel: Use-after-free in snd_pcm_info function in ALSA subsystem
potentially leads to privilege escalation (CVE-2017-0861)

* kernel: Handling of might_cancel queueing is not properly pretected
against race (CVE-2017-10661)

* kernel: Salsa20 encryption algorithm does not correctly handle
zero-length inputs allowing local attackers to cause denial of service
(CVE-2017-17805)

* kernel: Inifinite loop vulnerability in madvise_willneed() function
allows local denial of service (CVE-2017-18208)

* kernel: fuse-backed file mmap-ed onto process cmdline arguments
causes denial of service (CVE-2018-1120)

* kernel: a NULL pointer dereference in dccp_write_xmit() leads to a
system crash (CVE-2018-1130)

* kernel: drivers/block/loop.c mishandles lo_release serialization
allowing denial of service (CVE-2018-5344)

* kernel: Missing length check of payload in _sctp_make_chunk()
function allows denial of service (CVE-2018-5803)

* kernel: buffer overflow in drivers/net/wireless/ath/wil6210/
wmi.c:wmi_set_ie() may lead to memory corruption (CVE-2018-5848)

* kernel: out-of-bound write in ext4_init_block_bitmap function with a
crafted ext4 image (CVE-2018-10878)

* kernel: Improper validation in bnx2x network card driver can allow
for denial of service attacks via crafted packet (CVE-2018-1000026)

* kernel: Information leak when handling NM entries containing NUL
(CVE-2016-4913)

* kernel: Mishandling mutex within libsas allowing local Denial of

    descriptionSeveral vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2015-9016 Ming Lei reported a race condition in the multiqueue block layer (blk-mq). On a system with a driver using blk-mq (mtip32xx, null_blk, or virtio_blk), a local user might be able to use this for denial of service or possibly for privilege escalation. - CVE-2017-0861 Robb Glasser reported a potential use-after-free in the ALSA (sound) PCM core. We believe this was not possible in practice. - CVE-2017-5715 Multiple researchers have discovered a vulnerability in various processors supporting speculative execution, enabling an attacker controlling an unprivileged process to read memory from arbitrary addresses, including from the kernel and all other processes running on the system. This specific attack has been named Spectre variant 2 (branch target injection) and is mitigated for the x86 architecture (amd64 and i386) by using the

    descriptionAn update for kernel is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. The kernel packages contain the Linux kernel, the core of any Linux operating system.

  • NASL familyHuawei Local Security Checks
    NASL idEULEROS_SA-2019-2353.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):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. The ipddp_ioctl function in drivers et/appletalk/ipddp.c allows local users to obtain sensitive kernel address information by leveraging CAP_NET_ADMIN to read the ipddp_route dev and next fields via an SIOCFINDIPDDPRT ioctl call.(CVE-2018-20511)An issue was discovered in the Linux kernel before 4.18.7. In block/blk-core.c, there is an __blk_drain_queue() use-after-free because a certain error case is mishandled.(CVE-2018-20856)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)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 )Insufficient access control in the Intel(R) PROSet/Wireless WiFi Software driver before version 21.10 may allow an unauthenticated user to potentially enable denial of service via adjacent access.(CVE-2019-0136)A vulnerability was found in Linux kernel
