Security update for Linux Kernel Live Patch 18 for SLE 12 (important)

This update for the Linux Kernel 3.12.60-52_63 fixes several issues.

The following security bugs were fixed:

• CVE-2016-9806: Race condition in the netlink_dump function in
  net/netlink/af_netlink.c in the Linux kernel allowed local users to
  cause a denial of service (double free) or possibly have unspecified
  other impact via a crafted application that made sendmsg system calls,
  leading to a free operation associated with a new dump that started
  earlier than anticipated (bsc#1017589).
