This update for the Linux Kernel 3.12.67-60_64_21 fixes several issues.
The following security bugs were fixed:
- CVE-2016-9794: Race condition in the snd_pcm_period_elapsed function in
sound/core/pcm_lib.c in the ALSA subsystem in the Linux kernel allowed
local users to cause a denial of service (use-after-free) or possibly
have unspecified other impact via a crafted SNDRV_PCM_TRIGGER_START
command (bsc#1013543).
- CVE-2016-9576: The blk_rq_map_user_iov function in block/blk-map.c in
the Linux kernel did not properly restrict the type of iterator, which
allowed local users to read or write to arbitrary kernel memory
locations or cause a denial of service (use-after-free) by leveraging
access to a /dev/sg device (bsc#1014271).
