Remediation
Red Hat statement
This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise MRG as it does not have support for the S390 architecture. A future kernel update in Red Hat Enterprise Linux 6 may address this flaw. Red Hat Enterprise Linux 4 is now in Production 3 of the maintenance life-cycle, https://access.redhat.com/support/policy/updates/errata/, therefore the fix for this issue is not currently planned to be included in the future updates. This has been addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2011-0429.html.
