    An update that solves 7 vulnerabilities and has 44 fixes is now available.

    Description:

    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)
