Security update for Linux Kernel Live Patch 3 for SLE 12 SP2 (important)

This update for the Linux Kernel 4.4.21-90 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).
