The kernel-rt 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.

Users are advised to upgrade to these updated packages, which upgrade the
kernel-rt kernel to version kernel-rt-3.10.58-rt62.60 and correct this
issue. The system must be rebooted for this update to take effect.
