(RHSA-2016:2126) Important: kernel security update

The kernel packages contain the Linux kernel, the core of any Linux operating
system.

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.
