Red Hat Security Advisory 2011-1212-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A NULL pointer dereference flaw was found in the Linux kernel's Stream Control Transmission Protocol implementation. A remote attacker could send a specially-crafted SCTP packet to a target system, resulting in a denial of service. A flaw in the Linux kernel's client-side NFS Lock Manager implementation could allow a local, unprivileged user to cause a denial of service.
