is related to LU-8758 kernel update [RHEL6.8 2.6.32-642.6.2... Resolved
Severity: 3
Rank (Obsolete): 9223372036854775807

 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
