| Red Hat | 2010-02-04 | Mark J Cox | This issue did not affect the version of the Linux kernel as shipped with Red Hat Enterprise MRG as the affected driver is not enabled in this kernel. It was addressed in Red Hat Enterprise Linux 4 and 5 via https://rhn.redhat.com/errata/RHSA-2010-0076.html and https://rhn.redhat.com/errata/RHSA-2010-0046.html respectively. Red Hat Enterprise Linux 3 is now in Production 3 of the maintenance life-cycle, http://www.redhat.com/security/updates/errata, and this issue is rated as having low impact, therefore the fix for this issue is not currently planned to be included in the future updates. |
