Red Hat Security Advisory 2014-0557-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A race condition leading to a use-after-free flaw was found in the way the Linux kernel's TCP/IP protocol suite implementation handled the addition of fragments to the LRU list under certain conditions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system by sending a large amount of specially crafted fragmented packets to that system.
