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

These updated packages fix the following security issues:

a flaw was found in the SOCKOPS_WRAP macro in the Linux kernel. This
macro did not initialize the sendpage operation in the proto_ops structure
correctly. A local, unprivileged user could use this flaw to cause a local
denial of service or escalate their privileges. (CVE-2009-2692, Important)
a flaw was found in the udp_sendmsg() implementation in the Linux kernel
when using the MSG_MORE flag on UDP sockets. A local, unprivileged user
could use this flaw to cause a local denial of service or escalate their
privileges. (CVE-2009-2698, Important)

Red Hat would like to thank Tavis Ormandy and Julien Tinnes of the Google
Security Team for responsibly reporting these flaws.

Users should upgrade to these updated packages, which contain backported
patches to correct these issues. The system must be rebooted for this
update to take effect.
