Red Hat Security Advisory 2013-0830-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Red Hat Enterprise Linux 6.1 kernel update introduced an integer conversion issue in the Linux kernel's Performance Events implementation. This led to a user-supplied index into the perf_swevent_enabled array not being validated properly, resulting in out-of-bounds kernel memory access. A local, unprivileged user could use this flaw to escalate their privileges.
