"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)"
