Red Hat Security Advisory 2014-0108-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. It was found that the Xen hypervisor did not always lock 'page_alloc_lock' and 'grant_table.lock' in the same order. This could potentially lead to a deadlock. A malicious guest administrator could use this flaw to cause a denial of service on the host.
