Red Hat Security Advisory 2012-1282-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: It was found that a deadlock could occur in the Out of Memory killer. A process could trigger this deadlock by consuming a large amount of memory, and then causing request_module() to be called. A local, unprivileged user could use this flaw to cause a denial of service.
