    on the powerpc platform.
    arch/powerpc/kernel/idle_book3s.S does not have
    save/restore functionality for PNV_POWERSAVE_AMR,
    PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka
    CID-53a712bae5dd.(CVE-2020-11669)

  - In the Linux kernel before 5.6.1,
    drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink
    camera USB driver) mishandles invalid descriptors, aka
    CID-a246b4d54770.(CVE-2020-11668)

  - In the Linux kernel before 5.4.12,
    drivers/input/input.c has out-of-bounds writes via a
    crafted keycode table, as demonstrated by
    input_set_keycode, aka
    CID-cb222aed03d7.(CVE-2019-20636)

  - An issue was discovered in the Linux kernel before
    5.6.1. drivers/media/usb/gspca/ov519.c allows NULL
    pointer dereferences in ov511_mode_init_regs and
    ov518_mode_init_regs when there are zero endpoints, aka
    CID-998912346c0d.(CVE-2020-11608)

  - An issue was discovered in the stv06xx subsystem in the
    Linux kernel before 5.6.1.
    drivers/media/usb/gspca/stv06xx/stv06xx.c and
    drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c
    mishandle invalid descriptors, as demonstrated by a
    NULL pointer dereference, aka
    CID-485b06aadb93.(CVE-2020-11609)

  - A flaw was found in the Linux kernel's implementation
    of some networking protocols in IPsec, such as VXLAN
    and GENEVE tunnels over IPv6. When an encrypted tunnel
    is created between two hosts, the kernel isn't
    correctly routing tunneled data over the encrypted link
    rather sending the data unencrypted. This would allow
    anyone in between the two endpoints to read the traffic
    unencrypted. The main threat from this vulnerability is
    to data confidentiality.(CVE-2020-1749)

  - An issue was discovered in the Linux kernel through
    5.6.2. mpol_parse_str in mm/mempolicy.c has a
    stack-based out-of-bounds write because an empty
    nodelist is mishandled during mount option parsing, aka
    CID-aa9f7d5172fa.(CVE-2020-11565)

  - An issue was discovered in slc_bump in
    drivers/net/can/slcan.c in the Linux kernel through
    5.6.2. It allows attackers to read uninitialized
    can_frame data, potentially containing sensitive
    information from kernel stack memory, if the
    configuration lacks CONFIG_INIT_STACK_ALL, aka
    CID-b9258a2cece4.(CVE-2020-11494)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel
    through 5.3.12 allows a NULL pointer dereference
    because rcu_dereference(root->node) can be
    zero.(CVE-2019-19036)

  - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel
    through 5.3.12 allows a NULL pointer dereference
    because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be
    zero.(CVE-2019-19037)

  - __btrfs_free_extent in fs/btrfs/extent-tree.c in the
    Linux kernel through 5.3.12 calls btrfs_print_leaf in a
    certain ENOENT case, which allows local users to obtain
    potentially sensitive information about register values
    via the dmesg program.(CVE-2019-19039)

  - In the Linux kernel 5.0.21, mounting a crafted f2fs
    filesystem image can cause a NULL pointer dereference
    in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This
    is related to F2FS_P_SB in
    fs/f2fs/f2fs.h.(CVE-2019-19815)

  - In the AppleTalk subsystem in the Linux kernel before
    5.1, there is a potential NULL pointer dereference
    because register_snap_client may return NULL. This will
    lead to denial of service in net/appletalk/aarp.c and
    net/appletalk/ddp.c, as demonstrated by
    unregister_snap_client, aka

  - A memory leak in the adis_update_scan_mode() function
    in drivers/iio/imu/adis_buffer.c in the Linux kernel
    before 5.3.9 allows attackers to cause a denial of
    service (memory consumption), aka
    CID-ab612b1daf41.(CVE-2019-19060)

  - In the Linux kernel before 5.3.11, there is an

    USB device in the drivers/hid/usbhid/hiddev.c driver,
    aka CID-9c09b214f30e.(CVE-2019-19527)

  - ** DISPUTED ** The Linux kernel through 5.0.7, when
    CONFIG_IA32_AOUT is enabled and ia32_aout is loaded,
    allows local users to bypass ASLR on setuid a.out
    programs (if any exist) because install_exec_creds() is
    called too late in load_aout_binary() in
    fs/binfmt_aout.c, and thus the ptrace_may_access()
    check has a race condition when reading /proc/pid/stat.
    NOTE: the software maintainer disputes that this is a
    vulnerability because ASLR for a.out format executables
    has never been supported.(CVE-2019-11191)

  - In the Linux kernel before 5.3.12, there is a
    use-after-free bug that can be caused by a malicious
    USB device in the drivers/input/ff-memless.c driver,
    aka CID-fa3a5a1880c9.(CVE-2019-19524)

  - drivers/net/wireless/marvell/libertas/if_sdio.c in the
    Linux kernel 5.2.14 does not check the alloc_workqueue
    return value, leading to a NULL pointer
    dereference.(CVE-2019-16232)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14
    does not check the alloc_workqueue return value,
    leading to a NULL pointer dereference.(CVE-2019-16231)

  - ** DISPUTED **
    drivers/gpu/drm/amd/amdkfd/kfd_interrupt.c in the Linux
    kernel 5.2.14 does not check the alloc_workqueue return
    value, leading to a NULL pointer dereference. NOTE: The
    security community disputes this issues as not being
    serious enough to be deserving a CVE
    id.(CVE-2019-16229)

  - Linux kernel CIFS implementation, version 4.9.0 is
    vulnerable to a relative paths injection in directory
    entry lists.(CVE-2019-10220)

  - A heap overflow flaw was found in the Linux kernel, all
    versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi
    chip driver. The vulnerability allows a remote attacker
    to cause a system crash, resulting in a denial of
    service, or execute arbitrary code. The highest threat
    with this vulnerability is with the availability of the
    system. If code execution occurs, the code will run
    with the permissions of root. This will affect both
    confidentiality and integrity of files on the
    system.(CVE-2019-14901)

  - The Linux kernel before 5.4.2 mishandles
    ext4_expand_extra_isize, as demonstrated by
    use-after-free errors in __ext4_expand_extra_isize and
    ext4_xattr_set_entry, related to fs/ext4/inode.c and
    fs/ext4/super.c, aka CID-4ea99936a163.(CVE-2019-19767)

  - A heap-based buffer overflow was discovered in the
    Linux kernel, all versions 3.x.x and 4.x.x before
    4.18.0, in Marvell WiFi chip driver. The flaw could
    occur when the station attempts a connection
    negotiation during the handling of the remote devices
    country settings. This could allow the remote device to
    cause a denial of service (system crash) or possibly
    execute arbitrary code.(CVE-2019-14895)

  - Linux Kernel could allow a local authenticated attacker
    to obtain sensitive information, caused by a
    Transaction Asynchronous Abort (TAA) h/w issue in KVM.
    By sending a specially-crafted request, an attacker
    could exploit this vulnerability to obtain sensitive
    information, and use this information to launch further
    attacks against the affected system.(CVE-2019-19338)

  - TSX Asynchronous Abort condition on some CPUs utilizing
    speculative execution may allow an authenticated user
    to potentially enable information disclosure via a side
    channel with local access.(CVE-2019-11135)

  - An out-of-bounds memory write issue was found in the
    Linux Kernel, version 3.13 through 5.4, in the way the
    Linux kernel's KVM hypervisor handled the
    'KVM_GET_EMULATED_CPUID' ioctl(2) request to get CPUID
    features emulated by the KVM hypervisor. A user or
    process able to access the '/dev/kvm' device could use
    this flaw to crash the system, resulting in a denial of
    service.(CVE-2019-19332)

  - kernel/sched/fair.c in the Linux kernel before 5.3.9,
    when cpu.cfs_quota_us is used (e.g., with Kubernetes),
    allows attackers to cause a denial of service against
    non-cpu-bound applications by generating a workload
    that triggers unwanted slice expiration, aka
    CID-de53fd7aedb1. (In other words, although this slice
    expiration would typically be seen with benign
    workloads, it is possible that an attacker could
    calculate how many stray requests are required to force
    an entire Kubernetes cluster into a low-performance
    state caused by slice expiration, and ensure that a
    DDoS attack sent that number of stray requests. An
    attack does not affect the stability of the kernel it
    only causes mismanagement of application
    execution.)(CVE-2019-19922)

  - A stack-based buffer overflow was found in the Linux
    kernel, version kernel-2.6.32, in Marvell WiFi chip
    driver. An attacker is able to cause a denial of
    service (system crash) or, possibly execute arbitrary
    code, when a STA works in IBSS mode (allows connecting
    stations together without the use of an AP) and
    connects to another STA.(CVE-2019-14897)

  - A heap-based buffer overflow vulnerability was found in
    the Linux kernel, version kernel-2.6.32, in Marvell
    WiFi chip driver. A remote attacker could cause a
    denial of service (system crash) or, possibly execute
    arbitrary code, when the lbs_ibss_join_existing
    function is called after a STA connects to an
    AP.(CVE-2019-14896)

  - In the Linux kernel through 5.4.6, there are
    information leaks of uninitialized memory to a USB
    device in the
    drivers/net/can/usb/kvaser_usb/kvaser_usb_leaf.c
    driver, aka CID-da2311a6385c.(CVE-2019-19947)

  - In the Linux kernel before 5.1, there is a memory leak
    in __feat_register_sp() in net/dccp/feat.c, which may
    cause denial of service, aka
    CID-1d3ff0950e2b.(CVE-2019-20096)

  - mwifiex_tm_cmd in
    drivers/net/wireless/marvell/mwifiex/cfg80211.c in the
    Linux kernel before 5.1.6 has some error-handling cases
    that did not free allocated hostcmd memory, aka
    CID-003b686ace82. This will cause a memory leak and
    denial of service.(CVE-2019-20095)

  - An exploitable denial-of-service vulnerability exists
    in the Linux kernel prior to mainline 5.3. An attacker
    could exploit this vulnerability by triggering AP to
    send IAPP location updates for stations before the
    required authentication process has completed. This
    could lead to different denial-of-service scenarios,
    either by causing CAM table attacks, or by leading to
    traffic flapping if faking already existing clients in
    other nearby APs of the same wireless infrastructure.
    An attacker can forge Authentication and Association
    Request packets to trigger this
    vulnerability.(CVE-2019-5108)

  - In a Linux KVM guest that has PV TLB enabled, a process
    in the guest kernel may be able to read memory
    locations from another process in the same guest. This
    problem is limit to the host running linux kernel 4.10
    with a guest running linux kernel 4.16 or later. The
    problem mainly affects AMD processors but Intel CPUs
    cannot be ruled out.(CVE-2019-3016)

  - fs/namei.c in the Linux kernel before 5.5 has a
    may_create_in_sticky use-after-free, which allows local
    users to cause a denial of service (OOPS) or possibly
    obtain sensitive information from kernel memory, aka
    CID-d0cb50185ae9. One attack vector may be an open
    system call for a UNIX domain socket, if the socket is
    being moved to a new parent directory and its old
    parent directory is being removed.(CVE-2020-8428)

  - There is a use-after-free vulnerability in the Linux
    kernel through 5.5.2 in the n_tty_receive_buf_common
    function in drivers/tty/n_tty.c.(CVE-2020-8648)

  - An issue was discovered in the Linux kernel through
    5.5.6. set_fdc in drivers/block/floppy.c leads to a
    wait_til_ready out-of-bounds read because the FDC index
    is not checked for errors before assigning it, aka
    CID-2e90ca68b0d2.(CVE-2020-9383)

  - There is a use-after-free vulnerability in the Linux
    kernel through 5.5.2 in the vgacon_invert_region
    function in
    drivers/video/console/vgacon.c.(CVE-2020-8649)

  - There is a use-after-free vulnerability in the Linux
    kernel through 5.5.2 in the vc_do_resize function in
    drivers/tty/vt/vt.c.(CVE-2020-8647)

  - In the Linux kernel 5.0.21, mounting a crafted ext4
    filesystem image, performing some operations, and
    unmounting can lead to a use-after-free in
    ext4_put_super in fs/ext4/super.c, related to
    dump_orphan_list in fs/ext4/super.c.(CVE-2019-19447)

  - A flaw was discovered in the way that the KVM
    hypervisor handled instruction emulation for an L2
    guest when nested virtualisation is enabled. Under some
    circumstances, an L2 guest may trick the L0 guest into
    accessing sensitive L1 resources that should be
    inaccessible to the L2 guest.(CVE-2020-2732)

  - In the Linux kernel before 5.3.11, sound/core/timer.c
    has a use-after-free caused by erroneous code
    refactoring, aka CID-e7af6307a8a5. This is related to
    snd_timer_open and snd_timer_close_locked. The timeri
    variable was originally intended to be for a newly
    created timer instance, but was used for a different
    purpose after refactoring.(CVE-2019-19807)

  - In the Linux kernel 5.4.0-rc2, there is a
    use-after-free (read) in the __blk_add_trace function
    in kernel/trace/blktrace.c (which is used to fill out a
    blk_io_trace structure and place it in a per-cpu
    sub-buffer).(CVE-2019-19768)

  - In the Linux kernel 5.0.21, mounting a crafted f2fs
    filesystem image can cause a NULL pointer dereference
    in f2fs_recover_fsync_data in fs/f2fs/recovery.c. This
    is related to F2FS_P_SB in
    fs/f2fs/f2fs.h.(CVE-2019-19815)

  - ** DISPUTED ** __btrfs_free_extent in
    fs/btrfs/extent-tree.c in the Linux kernel through
    5.3.12 calls btrfs_print_leaf in a certain ENOENT case,
    which allows local users to obtain potentially
    sensitive information about register values via the
    dmesg program. NOTE: The BTRFS development team
    disputes this issues as not being a vulnerability
    because '1) The kernel provide facilities to restrict
    access to dmesg - dmesg_restrict=1 sysctl option. So
    it's really up to the system administrator to judge
    whether dmesg access shall be disallowed or not. 2)
    WARN/WARN_ON are widely used macros in the linux
    kernel. If this CVE is considered valid this would mean
    there are literally thousands CVE lurking in the kernel
    - something which clearly is not the
    case.'(CVE-2019-19039)

  - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel
    through 5.3.12 allows a NULL pointer dereference
    because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be
    zero.(CVE-2019-19037)

  - btrfs_root_node in fs/btrfs/ctree.c in the Linux kernel
    through 5.3.12 allows a NULL pointer dereference
    because rcu_dereference(root->node) can be
    zero.(CVE-2019-19036)

  - In the Linux kernel 4.19.83, there is a use-after-free
    (read) in the debugfs_remove function in
    fs/debugfs/inode.c (which is used to remove a file or
    directory in debugfs that was previously created with a
    call to another debugfs function such as
    debugfs_create_file).(CVE-2019-19770)

  - An issue was discovered in slc_bump in
    drivers/net/can/slcan.c in the Linux kernel through
    5.6.2. It allows attackers to read uninitialized
    can_frame data, potentially containing sensitive
    information from kernel stack memory, if the
    configuration lacks CONFIG_INIT_STACK_ALL, aka
    CID-b9258a2cece4.(CVE-2020-11494)

  - An issue was discovered in the Linux kernel through
    5.6.2. mpol_parse_str in mm/mempolicy.c has a
    stack-based out-of-bounds write because an empty
    nodelist is mishandled during mount option parsing, aka
    CID-aa9f7d5172fa.(CVE-2020-11565)

  - A flaw was found in the Linux kernel's implementation
    of some networking protocols in IPsec, such as VXLAN
    and GENEVE tunnels over IPv6. When an encrypted tunnel
    is created between two hosts, the kernel isn't
    correctly routing tunneled data over the encrypted link
    rather sending the data unencrypted. This would allow
    anyone in between the two endpoints to read the traffic
    unencrypted. The main threat from this vulnerability is
    to data confidentiality.(CVE-2020-1749)

  - An issue was discovered in the stv06xx subsystem in the
    Linux kernel before 5.6.1.
    drivers/media/usb/gspca/stv06xx/stv06xx.c and
    drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c
    mishandle invalid descriptors, as demonstrated by a
    NULL pointer dereference, aka
    CID-485b06aadb93.(CVE-2020-11609)

  - An issue was discovered in the Linux kernel before
    5.6.1. drivers/media/usb/gspca/ov519.c allows NULL
    pointer dereferences in ov511_mode_init_regs and
    ov518_mode_init_regs when there are zero endpoints, aka
    CID-998912346c0d.(CVE-2020-11608)

  - In the Linux kernel before 5.4.12,
    drivers/input/input.c has out-of-bounds writes via a
    crafted keycode table, as demonstrated by
    input_set_keycode, aka
    CID-cb222aed03d7.(CVE-2019-20636)

  - In the Linux kernel before 5.6.1,
    drivers/media/usb/gspca/xirlink_cit.c (aka the Xirlink
    camera USB driver) mishandles invalid descriptors, aka
    CID-a246b4d54770.(CVE-2020-11668)

  - An issue was discovered in the Linux kernel through
    5.6.2. mpol_parse_str in mm/mempolicy.c has a
    stack-based out-of-bounds write because an empty
    nodelist is mishandled during mount option parsing, aka
    CID-aa9f7d5172fa.(CVE-2020-0067)

  - An issue was discovered in the Linux kernel before 5.2
    on the powerpc platform.
    arch/powerpc/kernel/idle_book3s.S does not have
    save/restore functionality for PNV_POWERSAVE_AMR,
    PNV_POWERSAVE_UAMOR, and PNV_POWERSAVE_AMOR, aka
    CID-53a712bae5dd.(CVE-2020-11669)

    descriptionThis update is now available for all supported architectures. For reference the original advisory text follows. Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2015-8839 A race condition was found in the ext4 filesystem implementation. A local user could exploit this to cause a denial of service (filesystem corruption). CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613 Wen Xu from SSLab at Gatech reported that crafted Btrfs volumes could trigger a crash (Oops) and/or out-of-bounds memory access. An attacker able to mount such a volume could use this to cause a denial of service or possibly for privilege escalation. CVE-2019-5108 Mitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations. CVE-2019-19319 Jungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation. CVE-2019-19447 It was discovered that the ext4 filesystem driver did not safely handle unlinking of an inode that, due to filesystem corruption, already has a link count of 0. An attacker able to mount arbitrary ext4 volumes could use this to cause a denial of service (memory corruption or crash) or possibly for privilege escalation. CVE-2019-19768 Tristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation. CVE-2019-20636 The syzbot tool found that the input subsystem did not fully validate keycode changes, which could result in a heap out-of-bounds write. A local user permitted to access the device node for an input or VT device could possibly use this to cause a denial of service (crash or memory corruption) or for privilege escalation.

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

CVE-2015-8839

A race condition was found in the ext4 filesystem implementation. A
local user could exploit this to cause a denial of service (filesystem
corruption).

CVE-2018-14610, CVE-2018-14611, CVE-2018-14612, CVE-2018-14613

Wen Xu from SSLab at Gatech reported that crafted Btrfs volumes could
trigger a crash (Oops) and/or out-of-bounds memory access. An attacker
able to mount such a volume could use this to cause a denial of
service or possibly for privilege escalation.

CVE-2019-5108

Mitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi)
stack was used in AP mode with roaming, it would trigger roaming for a
newly associated station before the station was authenticated. An
attacker within range of the AP could use this to cause a denial of
service, either by filling up a switching table or by redirecting
traffic away from other stations.

CVE-2019-19319

Jungyeon discovered that a crafted filesystem can cause the ext4
implementation to deallocate or reallocate journal blocks. A user
permitted to mount filesystems could use this to cause a denial of
service (crash), or possibly for privilege escalation.

CVE-2019-19447

It was discovered that the ext4 filesystem driver did not safely
handle unlinking of an inode that, due to filesystem corruption,
already has a link count of 0. An attacker able to mount arbitrary
ext4 volumes could use this to cause a denial of service (memory
corruption or crash) or possibly for privilege escalation.

CVE-2019-19768

Tristan Madani reported a race condition in the blktrace debug
facility that could result in a use-after-free. A local user able to
trigger removal of block devices could possibly use this to cause a
denial of service (crash) or for privilege escalation.

CVE-2019-20636

The syzbot tool found that the input subsystem did not fully validate
keycode changes, which could result in a heap out-of-bounds write. A
local user permitted to access the device node for an input or VT
device could possibly use this to cause a denial of service (crash or
memory corruption) or for privilege escalation.

CVE-2020-0009

Jann Horn reported that the Android ashmem driver did not prevent
read-only files from being memory-mapped and then remapped as
read-write. However, Android drivers are not enabled in Debian kernel
configurations.

CVE-2020-0543

Researchers at VU Amsterdam discovered that on some Intel CPUs
supporting the RDRAND and RDSEED instructions, part of a random value
generated by these instructions may be used in a later speculative
execution on any core of the same physical CPU. Depending on how these
instructions are used by applications, a local user or VM guest could
use this to obtain sensitive information such as cryptographic keys
from other users or VMs.

This vulnerability can be mitigated by a microcode update,
either as part of system firmware (BIOS) or through the
intel-microcode package in Debian's non-free archive
section. This kernel update only provides reporting of the
vulnerability and the option to disable the mitigation if it
is not needed.

CVE-2020-1749

Xiumei Mu reported that some network protocols that can run on top of
IPv6 would bypass the Transformation (XFRM) layer used by IPsec,
IPcomp/IPcomp6, IPIP, and IPv6 Mobility. This could result in
disclosure of information over the network, since it would not be
encrypted or routed according to the system policy.

CVE-2020-2732

Paulo Bonzini discovered that the KVM implementation for Intel
processors did not properly handle instruction emulation for L2 guests
when nested virtualization is enabled. This could allow an L2 guest to
cause privilege escalation, denial of service, or information leaks in
the L1 guest.

CVE-2020-8647, CVE-2020-8649

The Hulk Robot tool found a potential MMIO out-of-bounds access in the
vgacon driver. A local user permitted to access a virtual terminal
(/dev/tty1 etc.) on a system using the vgacon driver could use this to
cause a denial of service (crash or memory corruption) or possibly for
privilege escalation.

CVE-2020-8648

The syzbot tool found a race condition in the the virtual terminal
driver, which could result in a use-after-free. A local user permitted
to access a virtual terminal could use this to cause a denial of
service (crash or memory corruption) or possibly for privilege
escalation.

CVE-2020-9383

Jordy Zomer reported an incorrect range check in the floppy driver
which could lead to a static out-of-bounds access. A local user
permitted to access a floppy drive could use this to cause a denial of
service (crash or memory corruption) or possibly for privilege
escalation.

CVE-2020-10690

It was discovered that the PTP hardware clock subsystem did not
properly manage device lifetimes. Removing a PTP hardware clock from
the system while a user process was using it could lead to a
use-after-free. The security impact of this is unclear.

CVE-2020-10751

Dmitry Vyukov reported that the SELinux subsystem did not properly
handle validating multiple messages, which could allow a privileged
attacker to bypass SELinux netlink restrictions.

CVE-2020-10942

It was discovered that the vhost_net driver did not properly validate
the type of sockets set as back-ends. A local user permitted to access
/dev/vhost-net could use this to cause a stack corruption via crafted
system calls, resulting in denial of service (crash) or possibly
privilege escalation.

CVE-2020-11494

It was discovered that the slcan (serial line CAN) network driver did
not fully initialise CAN headers for received packets, resulting in an
information leak from the kernel to user-space or over the CAN
network.

CVE-2020-11565

Entropy Moe reported that the shared memory filesystem (tmpfs) did not
correctly handle an 'mpol' mount option specifying an empty node list,
leading to a stack-based out-of-bounds write. If user namespaces are
enabled, a local user could use this to cause a denial of service
(crash) or possibly for privilege escalation.

CVE-2020-11608, CVE-2020-11609, CVE-2020-11668

It was discovered that the ov519, stv06xx, and xirlink_cit media
drivers did not properly validate USB device descriptors. A physically
present user with a specially constructed USB device could use this to
cause a denial of service (crash) or possibly for privilege
escalation.

CVE-2020-12114

Piotr Krysiuk discovered a race condition between the umount and
pivot_root operations in the filesystem core (vfs). A local user with
the CAP_SYS_ADMIN capability in any user namespace could use this to
cause a denial of service (crash).

CVE-2020-12464

Kyungtae Kim reported a race condition in the USB core that can result
in a use-after-free. It is not clear how this can be exploited, but it
could result in a denial of service (crash or memory corruption) or
privilege escalation.

CVE-2020-12652

Tom Hatskevich reported a bug in the mptfusion storage drivers. An
ioctl handler fetched a parameter from user memory twice, creating a
race condition which could result in incorrect locking of internal
data structures. A local user permitted to access /dev/mptctl could
use this to cause a denial of service (crash or memory corruption) or
for privilege escalation.

CVE-2020-12653

It was discovered that the mwifiex WiFi driver did not sufficiently
validate scan requests, resulting a potential heap buffer overflow. A
local user with CAP_NET_ADMIN capability could use this to cause a
denial of service (crash or memory corruption) or possibly for
privilege escalation.

CVE-2020-12654

It was discovered that the mwifiex WiFi driver did not sufficiently
validate WMM parameters received from an access point (AP), resulting
a potential heap buffer overflow. A malicious AP could use this to
cause a denial of service (crash or memory corruption) or possibly to
execute code on a vulnerable system.

CVE-2020-12769

It was discovered that the spi-dw SPI host driver did not properly
serialise access to its internal state. The security impact of this is
unclear, and this driver is not included in Debian's binary packages.

CVE-2020-12770

It was discovered that the sg (SCSI generic) driver did not correctly
release internal resources in a particular error case. A local user
permitted to access an sg device could possibly use this to cause a
denial of service (resource exhaustion).

CVE-2020-12826

Adam Zabrocki reported a weakness in the signal subsystem's permission
checks. A parent process can choose an arbitary signal for a child
process to send when it exits, but if the parent has executed a new
program then the default SIGCHLD signal is sent. A local user
permitted to run a program for several days could bypass this check,
execute a setuid program, and then send an arbitrary signal to it.
Depending on the setuid programs installed, this could have some
security impact.

CVE-2020-13143

Kyungtae Kim reported a potential heap out-of-bounds write in the USB
gadget subsystem. A local user permitted to write to the gadget
configuration filesystem could use this to cause a denial of service
(crash or memory corruption) or potentially for privilege escalation.

For Debian 8 'Jessie', these problems have been fixed in version
3.16.84-1.

We recommend that you upgrade your linux packages.

    descriptionAccording to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities : - In the Linux kernel 5.0.21, mounting a crafted btrfs filesystem image, performing some operations, and unmounting can lead to a use-after-free in btrfs_queue_work in fs/btrfs/async-thread.c.(CVE-2019-19377) - The fix for CVE-2019-11599, affecting the Linux kernel before 5.0.10 was not complete. A local user could use this flaw to obtain sensitive information, cause a denial of service, or possibly have other unspecified impacts by triggering a race condition with mmget_not_zero or get_task_mm calls.(CVE-2019-14898) - A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter.(CVE-2020-12114) - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because a transfer occurs without a reference, aka CID-056ad39ee925.(CVE-2020-12464) - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a
