Comment 10 Petr Matousek 2014-06-05 16:28:07 UTC 
Statement:

This issue did not affect the versions of the Linux kernel packages as shipped with Red Hat Enterprise Linux 5.

This issue requires local system access to be exploited. We are currently not aware of any working exploit for Red Hat Enterprise Linux 6 or Red Hat Enterprise MRG 2.
