"Security Fix(es) :

  - A use-after-free vulnerability was found in the kernels
    socket recvmmsg subsystem. This may allows remote
    attackers to corrupt memory and may allow execution of
    arbitrary code. This corruption takes place during the
    error handling routines within __sys_recvmmsg()
    function. (CVE-2016-7117, Important)

Bug Fix(es) :

  - Previously, guest virtual machines (VMs) on a Hyper-V
    server cluster got in some cases rebooted during the
    graceful node failover test, because the host kept
    sending heartbeat packets independently of guests
    responding to them. This update fixes the bug by
    properly responding to all the heartbeat messages in the
    queue, even if they are pending. As a result, guest VMs
    no longer get rebooted under the described
    circumstances."
