   An update that fixes two vulnerabilities is now available.

Description:


   The SUSE Linux Enterprise 12 SP 2 kernel was updated to fix two security
   issues.

   The following security bugs were fixed:

   - CVE-2016-9576: A use-after-free vulnerability in the SCSI generic driver
     allows users with write access to /dev/sg* or /dev/bsg* to elevate their
     privileges (bsc#1013604).
   - CVE-2016-9794: A use-after-free vulnerability in the ALSA pcm layer
     allowed local users to cause a denial of service, memory corruption or
     possibly even to elevate their privileges (bsc#1013533).
