Please Install the Updated Packages.
Insight
The kernel packages contain the Linux kernel, the core of any Linux operating system.
This update fixes the following security issue:
* A flaw was found in the way socket buffers (skb) requiring TSO (TCP segment offloading) were handled by the sfc driver. If the skb did not fit within the minimum-size of the transmission queue, the network card could repeatedly reset itself. A remote attacker could use this flaw to cause a denial of service. (CVE-2012-3412, Important)
Red Hat would like to thank Ben Hutchings of Solarflare (tm) for reporting this issue.
This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section.
Users should upgrade to these updated packages, which contain backported patches to correct this issue, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
