Description


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.
Please see https://www.redhat.com/footer/terms-of-use.html
