"Updated kernel packages that fix one security issue are now available
for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Important
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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

* A flaw was found in the way the Linux kernel handled GS segment
register base switching when recovering from a #SS (stack segment)
fault on an erroneous return to user space. A local, unprivileged user
could use this flaw to escalate their privileges on the system.
(CVE-2014-9322, Important)

Red Hat would like to thank Andy Lutomirski for reporting this issue.

All kernel users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The system
must be rebooted for this update to take effect."
