Remediation
Red Hat statement
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they do not have support for the I/O-Warrior USB devices. This has been addressed in Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-0330.html. A future kernel update in Red Hat Enterprise Linux 6 may address this flaw.
