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

  • It was found that the Linux kernel’s Infiniband subsystem did not
    properly sanitize input parameters while registering memory regions from
    user space via the (u)verbs API. A local user with access to a
    /dev/infiniband/uverbsX device could use this flaw to crash the system or,
    potentially, escalate their privileges on the system. (CVE-2014-8159,
    Important)

Red Hat would like to thank Mellanox 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.
