The Red Hat Security Response Team has rated this update as having

(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issue :
* The compat_alloc_user_space() function in the Linux kernel 32/64-bit
compatibility layer implementation was missing sanity checks. This
function could be abused in other areas of the Linux kernel if its
length argument can be controlled from user-space. On 64-bit systems,
a local, unprivileged user could use this flaw to escalate their
privileges. (CVE-2010-3081, Important)
