  script_tag(name:"insight", value:"This update for the Linux Kernel 3.12.55-52_45 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-2016-8632: The tipc_msg_build function in net/tipc/msg.c in the
 Linux kernel did not validate the relationship between the minimum
 fragment length and the maximum packet size, which allowed local users
 to gain privileges or cause a denial of service (heap-based buffer
 overflow) by leveraging the CAP_NET_ADMIN capability (bsc#1012852).
- 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).");
