Security Fix(es):
* A race condition was found in the way the Linux kernel's memory subsystem
handled the copy-on-write (COW) breakage of private read-only memory
mappings. An unprivileged, local user could use this flaw to gain write
access to otherwise read-only memory mappings and thus increase their
privileges on the system. (CVE-2016-5195, Important)
Red Hat would like to thank Phil Oester for reporting this issue.");
