Security update for Linux Kernel Live Patch 2 for SLE 12 SP2 (important)

This update for the Linux Kernel 4.4.21-84 fixes several issues.

The following security bugs were fixed:

• CVE-2016-10088: The sg implementation in the Linux kernel did not
  properly restrict write operations in situations where the KERNEL_DS
  option is set, 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, related to block/bsg.c and
  drivers/scsi/sg.c. NOTE: this vulnerability exists because of an
  incomplete fix for CVE-2016-9576 (bsc#1019079).
• 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). before 4.8.14
