Red Hat Security Advisory 2014-1943-01 - The kernel-rt packages contain the Linux kernel, the core of any Linux operating system. A denial of service flaw was found in the way the Linux kernel's XFS file system implementation ordered directory hashes under certain conditions. A local attacker could use this flaw to corrupt the file system by creating directories with colliding hash values, potentially resulting in a system crash. An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system.
