Security update for the Linux Kernel (Live Patch 2 for SLE 12 SP3) (important)

This update for the Linux Kernel 4.4.82-6_6 fixes several issues.

The following security issues were fixed:

• CVE-2017-17712: The raw_sendmsg() function had a race condition that
  lead to uninitialized stack pointer usage. This allowed a local user to
  execute code and gain privileges (bsc#1073230).
• CVE-2017-16939: The XFRM dump policy implementation allowed local users
  to gain privileges or cause a denial of service (use-after-free) via a
  crafted SO_RCVBUF setsockopt system call in conjunction with
  XFRM_MSG_GETPOLICY Netlink messages (bsc#1069708).
