From https://bugzilla.redhat.com/show_bug.cgi?id=875374 :

A NULL pointer dereference flaw has been found in the way a new node's hot-added memory is 
propagated to other nodes zonelists. An unprivileged local user can use this flaw to crash the 
system.

There are no longer any 2.x or <3.6 kernels available in the repository with the exception of sys-kernel/xbox-sources which is unsupported by security.
