DESCRIPTION

* CVE-2017-7472: Denial-of-service when setting default request-key keyring.

A logic error when a user set default request-key keyring multiple
times could lead to a memory leak. A local attacker could use this flaw
to exhaust kernel memory and cause a kernel panic.


* CVE-2017-7308: Memory corruption in AF_PACKET socket options.

Multiple integer overflows in the AF_PACKET setsockopt implementation can
trigger kernel memory corruption. A local user could use this flaw to elevate
privileges.
