CentOS Errata and Security Advisory CESA-2010:0792

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

This update fixes the following security issue:

Red Hat would like to thank Dan Rosenberg of Virtual Security Research for reporting this issue.

Users should 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.
