|Bugzilla:||680000: CVE-2011-1016 kernel: drm/radeon/kms: check AA resolve registers on r300|
The MITRE CVE dictionary describes this issue as:
The Radeon GPU drivers in the Linux kernel before 2.6.38-rc5 do not properly validate data related to the AA resolve registers, which allows local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values.
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG as they did not backport the upstream commits fff1ce4d and 45e4039c that introduced this issue. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2011-0498.html.
