===================================================================== Red Hat Security Advisory
Synopsis: Important: kernel security update Advisory ID: RHSA-2016:2127-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-2127.html Issue date: 2016-10-31 CVE Names: CVE-2016-5195 =====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 5.6 Long Life.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Long Life (v. 5.6 server) - i386, ia64, noarch, x86_64
3. Description:
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.
4. Solution:
For details on how to apply this update, which includes the changes described in this advisory, refer to:
https://access.redhat.com/articles/11258
The system must be rebooted for this update to take effect.
5. Bugs fixed (https://bugzilla.redhat.com/):
1384344 - CVE-2016-5195 kernel: mm: privilege escalation via MAP_PRIVATE COW breakage
