This issue did not affect the version of the Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for ULE (Unidirectional Lightweight Encapsulation). We have included a fix for this issue in Red Hat Enterprise Linux 4 and 5 however the affected module is not build by default. This issue was addressed in Red Hat Enterprise MRG via http://rhn.redhat.com/errata/RHSA-2010-0631.html.
