Security update for Linux Kernel Live Patch 17 for SLE 12

This update for the Linux Kernel 3.12.60-52_60 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). - 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).
