Red Hat Security Advisory 2014-1724-01 – The kernel packages contain the Linux kernel, the core of any Linux operating system. Security fixes: A race condition flaw was found in the way the Linux kernel’s KVM subsystem handled PIT emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host. A NULL pointer dereference flaw was found in the way the Linux kernel’s Stream Control Transmission Protocol implementation handled simultaneous connections between the same hosts. A remote attacker could use this flaw to crash the system.
