"The SUSE Linux Enterprise 12 kernel was updated to 3.12.48-52.27 to
receive various security and bugfixes.

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 update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
