* CVE-2017-1000111: Privilege escalation when setting options on AF_PACKET socket.
A missing locking when setting options on AF_PACKET socket could lead to
an out-of-bounds access. A local attacker with CAP_NET_RAW capability,
or on a system with unprivileged namespace enabled, could use this flaw
to cause a denial-of-service or execute arbitrary code.
* CVE-2017-7542: Buffer overflow when parsing IPV6 fragments header.
An incorrect data type when parsing IPV6 fragments header could lead to
a buffer overflow and to an infinite loop. A remote attacker could use
this flaw to cause a denial-of-service.
* CVE-2017-11176: Use-after-free in message queue notify syscall.
A race condition when closing a message queue file descriptor could
