Description Eugene Teo (Security Response) 2011-02-24 03:39:07 UTC
Check values passed in to AARESOLVE_OFFSET on r300. It can be used to write
arbitrary data to VRAM, GTT, etc. This is specific to a range of GPUs only.

Comment 3 Eugene Teo (Security Response) 2011-02-25 01:15:58 UTC
Both patches have been committed to the upstream kernel.

Comment 4 Vincent Danen 2011-02-28 17:56:15 UTC
This was assigned CVE-2011-1016:

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 has been addressed in following products:

  Red Hat Enterprise Linux 6

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

Comment 6 Eugene Teo (Security Response) 2011-07-19 05:48:13 UTC
Statement:

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.
