Remediation
Red Hat statement
The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and 5 did not include CAN bus subsystem support, and therefore are not affected by this issue. 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.
