  script_tag(name:"insight", value:"The openSUSE Leap 42.3 kernel was
  updated to 4.4.162 to receive various security and bugfixes.

  The following security bugs were fixed:

  - CVE-2018-18281: The mremap() syscall performs TLB flushes after dropping
  pagetable locks. If a syscall such as ftruncate() removes entries from
  the pagetables of a task that is in the middle of mremap(), a stale TLB
  entry can remain for a short time that permits access to a physical page
  after it has been released back to the page allocator and reused.
  (bnc#1113769).

  - CVE-2018-18710: 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
  (bnc#1113751).

  - CVE-2018-18690: A local attacker able to set attributes on an xfs
  filesystem could make this filesystem non-operational until the next
  mount by triggering an unchecked error condition during an xfs attribute
  change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c
  mishandled ATTR_REPLACE operations with conversion of an attr from short
  to long form (bnc#1105025).

  - CVE-2018-18386: drivers/tty/n_tty.c allowed local attackers (who are
  able to access pseudo terminals) to hang/block further usage of any
  pseudo terminal devices due to an EXTPROC versus ICANON confusion in
  TIOCINQ (bnc#1094825).

  - CVE-2018-9516: A lack of certain checks in the hid_debug_events_read()
  function in the drivers/hid/hid-debug.c file might have resulted in
  receiving userspace buffer overflow and an out-of-bounds write or to the
  infinite loop. (bnc#1108498).

  The following non-security bugs were fixed:

  - 6lowpan: iphc: reset mac_header after decompress to fix panic
  (bnc#1012382).

  - Add azure kernel description.

  - Add bug reference to
  patches.suse/x86-entry-64-use-a-per-cpu-trampoline-stack-fix1.patch

  - Add graphviz to buildreq for image conversion

  - Add reference to bsc#1104124 to
  patches.fixes/fs-aio-fix-the-increment-of-aio-nr-and-counting-agai.patch

  - ALSA: hda: Add AZX_DCAPS_PM_RUNTIME for AMD Raven Ridge (bnc#1012382).

  - ALSA: hda/realtek - Cannot adjust speaker's volume on Dell XPS 27 7760
  (bnc#1012382).

  - apparmor: remove no-op permission check in policy_unpack (git-fixes).

  - ARC: build: Get rid of toolchain check (bnc#1012382).

  - ARC: clone syscall to setp r25 as thread pointer (bnc#1012382).

  - arch/hexagon: fix kernel/dma.c build warning (bnc#1012382).

  - arch-symbols: use bash as interpreter since the script uses bashism.
