Red Hat Security Advisory 2013-0741-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A race condition was found in the way the Linux kernel's ptrace implementation handled PTRACE_SETREGS requests when the debuggee was woken due to a SIGKILL signal instead of being stopped. A local, unprivileged user could use this flaw to escalate their privileges.

Red Hat Security Advisory 2013-0621-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way file permission checks for the "/dev/cpu/[x]/msr" files were performed in restricted root environments. A local user with the ability to write to these files could use this flaw to escalate their privileges to kernel level, for example, by writing to the SYSENTER_EIP_MSR register.
