Red Hat Security Advisory 2012-0862-04 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's Event Poll subsystem handled large, nested epoll structures. A local, unprivileged user could use this flaw to cause a denial of service. A malicious Network File System version 4 server could return a crafted reply to a GETACL request, causing a denial of service on the client.
