DESCRIPTION

* CVE-2016-2117: Information leak in Atheros ATL2 transmission.

The Atheros ATL2 driver advertised features that weren't supported by
the hardware and this could result in a buffer overflow, leaking the
contents of kernel memory into transmitted packets.


* CVE-2016-6197, CVE-2016-6198: Denial-of-service in OverlayFS on XFS.

Missing verification could result in a kernel crash for an OverlayFS
filesystem on XFS during unlink or renaming.  Additionally, incorrect
handling of hard links could result in a kernel crash during renaming.
