  Red Hat Enterprise Linux 6

Via RHSA-2011:0498 https://rhn.redhat.com/errata/RHSA-2011-0498.html

Comment 5 Eugene Teo (Security Response) 2011-07-19 01:27:35 EDT

Statement:

This issue did not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the driver for Native Instruments USB audio devices. It did not affect the Linux kernel as shipped with Red Hat Enterprise MRG as it did not enable support for this driver. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2011-0498.html.
