This issue did not affect the versions of Linux kernel as shipped with Red Hat
Enterprise Linux 4 as they did not backport the upstream commit b6a2fea3 that introduced the issue. This was addressed in Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0004.html and
https://rhn.redhat.com/errata/RHSA-2010-0958.html. Future kernel updates in Red Hat Enterprise Linux 6 may address this flaw.
