  script_tag(name:"insight", value:"The SUSE Linux Enterprise 12 kernel was updated to 3.12.48-52.27 to
  receive various security and bugfixes.

  The following security bugs were fixed:

  * CVE-2015-7613: A flaw was found in the Linux kernel IPC code that could
  lead to arbitrary code execution. The ipc_addid() function initialized a
  shared object that has unset uid/gid values. Since the fields are not
  initialized, the check can falsely succeed. (bsc#948536)

  * CVE-2015-5156: When a guests KVM network devices is in a bridge
  configuration the kernel can create a situation in which packets are
  fragmented in an unexpected fashion. The GRO functionality can create a
  situation in which multiple SKB's are chained together in a single
  packets fraglist (by design). (bsc#940776)

  * CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel before
  4.1.6 on the x86_64 platform mishandles IRET faults in processing NMIs
  that occurred during userspace execution, which might allow local users
  to gain privileges by triggering an NMI (bsc#938706).

  * CVE-2015-6252: A flaw was found in the way the Linux kernel's vhost
  driver treated userspace provided log file descriptor when processing
  the VHOST_SET_LOG_FD ioctl command. The file descriptor was never
  released and continued to consume kernel memory. A privileged local user
  with access to the /dev/vhost-net files could use this flaw to create a
  denial-of-service attack (bsc#942367).

  * CVE-2015-5697: The get_bitmap_file function in drivers/md/md.c in the
  Linux kernel before 4.1.6 does not initialize a certain bitmap data
  structure, which allows local users to obtain sensitive information from
  kernel memory via a GET_BITMAP_FILE ioctl call. (bnc#939994)

  * CVE-2015-6937: A NULL pointer dereference flaw was found in the Reliable
  Datagram Sockets (RDS) implementation allowing a local user to cause
  system DoS. A verification was missing that the underlying transport
  exists when a connection was created. (bsc#945825)

  * CVE-2015-5283: A NULL pointer dereference flaw was found in SCTP
  implementation allowing a local user to cause system DoS. Creation of
  multiple sockets in parallel when system doesn't have SCTP module loaded
  can lead to kernel panic. (bsc#947155)

  The following non-security bugs were fixed:

  - ALSA: hda - Abort the probe without i915 binding for HSW/BDW
  (bsc#936556).

  - Btrfs: Backport subvolume mount option handling (bsc#934962)

  - Btrfs: Handle unaligned length in extent_same (bsc#937609).

  - Btrfs: advertise which crc32c implementation is being used on mount
