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

  - CVE-2018-6554
    A memory leak in the irda_bind function in the irda
    subsystem was discovered. A local user can take
    advantage of this flaw to cause a denial of service
    (memory consumption).

  - CVE-2018-6555
    A flaw was discovered in the irda_setsockopt function in
    the irda subsystem, allowing a local user to cause a
    denial of service (use-after-free and system crash).

  - CVE-2018-7755
    Brian Belleville discovered a flaw in the
    fd_locked_ioctl function in the floppy driver in the
    Linux kernel. The floppy driver copies a kernel pointer
    to user memory in response to the FDGETPRM ioctl. A
    local user with access to a floppy drive device can take
    advantage of this flaw to discover the location kernel
    code and data.

  - CVE-2018-9363
    It was discovered that the Bluetooth HIDP implementation
    did not correctly check the length of received report
    messages. A paired HIDP device could use this to cause a
    buffer overflow, leading to denial of service (memory
    corruption or crash) or potentially remote code
    execution.

  - CVE-2018-9516
    It was discovered that the HID events interface in
    debugfs did not correctly limit the length of copies to
    user buffers. A local user with access to these files
    could use this to cause a denial of service (memory
    corruption or crash) or possibly for privilege
    escalation. However, by default debugfs is only
    accessible by the root user.

  - CVE-2018-10902
    It was discovered that the rawmidi kernel driver does
    not protect against concurrent access which leads to a
    double-realloc (double free) flaw. A local attacker can
    take advantage of this issue for privilege escalation.

  - CVE-2018-10938
    Yves Younan from Cisco reported that the Cipso IPv4
    module did not correctly check the length of IPv4
    options. On custom kernels with CONFIG_NETLABEL enabled,
    a remote attacker could use this to cause a denial of
    service (hang).

  - CVE-2018-13099
    Wen Xu from SSLab at Gatech reported a use-after-free
    bug in the F2FS implementation. An attacker able to
    mount a crafted F2FS volume could use this to cause a
    denial of service (crash or memory corruption) or
    possibly for privilege escalation.

  - CVE-2018-14609
    Wen Xu from SSLab at Gatech reported a potential NULL
    pointer dereference in the F2FS implementation. An
    attacker able to mount a crafted F2FS volume could use
    this to cause a denial of service (crash).

  - CVE-2018-14617
    Wen Xu from SSLab at Gatech reported a potential NULL
    pointer dereference in the HFS+ implementation. An
    attacker able to mount a crafted HFS+ volume could use
    this to cause a denial of service (crash).

  - CVE-2018-14633
    Vincent Pelletier discovered a stack-based buffer
    overflow flaw in the chap_server_compute_md5() function
    in the iSCSI target code. An unauthenticated remote
    attacker can take advantage of this flaw to cause a
    denial of service or possibly to get a non-authorized
    access to data exported by an iSCSI target.

  - CVE-2018-14678
    M. Vefa Bicakci and Andy Lutomirski discovered a flaw in
    the kernel exit code used on amd64 systems running as
    Xen PV guests. A local user could use this to cause a
    denial of service (crash).

  - CVE-2018-14734
    A use-after-free bug was discovered in the InfiniBand
    communication manager. A local user could use this to
    cause a denial of service (crash or memory corruption)
    or possible for privilege escalation.

  - CVE-2018-15572
    Esmaiel Mohammadian Koruyeh, Khaled Khasawneh, Chengyu
    Song, and Nael Abu-Ghazaleh, from University of
    California, Riverside, reported a variant of Spectre
    variant 2, dubbed SpectreRSB. A local user may be able
    to use this to read sensitive information from processes
    owned by other users.

  - CVE-2018-15594
    Nadav Amit reported that some indirect function calls
    used in paravirtualised guests were vulnerable to
    Spectre variant 2. A local user may be able to use this
    to read sensitive information from the kernel.

  - CVE-2018-16276
    Jann Horn discovered that the yurex driver did not
    correctly limit the length of copies to user buffers. A
    local user with access to a yurex device node could use
    this to cause a denial of service (memory corruption or
    crash) or possibly for privilege escalation.

  - CVE-2018-16658
    It was discovered that the cdrom driver does not
    correctly validate the parameter to the
    CDROM_DRIVE_STATUS ioctl. A user with access to a cdrom
    device could use this to read sensitive information from
    the kernel or to cause a denial of service (crash).

  - CVE-2018-17182
    Jann Horn discovered that the vmacache_flush_all
    function mishandles sequence number overflows. A local
    user can take advantage of this flaw to trigger a
    use-after-free, causing a denial of service (crash or
    memory corruption) or privilege escalation."
