An update that solves two vulnerabilities can now be installed.

Description:

The SUSE Linux Enterprise 12 kernel was updated to receive two security fixes.

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).

Special Instructions and Notes:

• Please reboot the system after installing this update.

Patch Instructions:

To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
