Description Eugene Teo (Security Response) 2011-02-16 04:02:39 UTC 
task_show_regs used to be a debugging aid in the early bringup days of Linux on s390. /proc/<pid>/status is a world readable file, it is not a good idea to show the registers of a process. The only correct fix is to remove task_show_regs.

Comment 3 Eugene Teo (Security Response) 2011-03-11 06:21:59 UTC 
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.
