Critical: kernel

Issue Overview:

Exploitable memory corruption due to UFO to non-UFO path switch (CVE-2017-1000112)

heap out-of-bounds in AF_PACKET sockets (CVE-2017-1000111)

The mq_notify function in the Linux kernel does not set the sock pointer to NULL upon entry into the retry logic. During a user-space close of a Netlink socket, it allows attackers to possibly cause a situation where a value may be used after being freed (use-after-free) which may lead to memory corruption or other unspecified other impact. (CVE-2017-11176 )
