      Description

      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)

      Bugs fixed (https://bugzilla.redhat.com/):

      1384344 - CVE-2016-5195 kernel: mm: privilege escalation via MAP_PRIVATE COW breakage
