Red Hat Security Advisory 2013-0911-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way KVM initialized a guest's registered pv_eoi indication flag when entering the guest. An unprivileged guest user could potentially use this flaw to crash the host. A missing sanity check was found in the kvm_set_memory_region() function in KVM, allowing a user-space process to register memory regions pointing to the kernel address space. A local, unprivileged user could use this flaw to escalate their privileges.
