    Description:

    The SUSE Linux Enterprise 11 Service Pack 3 kernel was updated to receive
    various security and bugfixes.

    Following security bugs were fixed:
    - CVE-2015-8104: Prevent guest to host DoS caused by infinite loop in
    microcode via #DB exception (bsc#954404).
    - CVE-2015-5307: Prevent guest to host DoS caused by infinite loop in
    microcode via #AC exception (bsc#953527).

    creating a connection, preventing possible DoS (bsc#952384).
    - CVE-2015-5157: arch/x86/entry/entry_64.S in the Linux kernel on the
    x86_64 platform mishandled IRET faults in processing NMIs that occurred
    during userspace execution, which might have allowed local users to gain
    privileges by triggering an NMI (bsc#938706).

    uninstantiated keyring (bsc#951440).

    impact by using a socket that was not properly bound (bsc#945825).
    - CVE-2015-6252: The vhost_dev_ioctl function in drivers/vhost/vhost.c in
