Statement
The Linux kernel as shipped with Red Hat Enterprise Linux 4 and Red Hat Enterprise MRG did not include support for the RDS Protocol, and therefore are
not affected by this issue. The Linux kernel as shipped with Red Hat Enterprise Linux 5 and 6 are not affected as they did not backport upstream commit 2e7b3b99 and 77dd550e that introduced this issue.
