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.
