Bug#690821: GPU driver changes from 2.6.32.59+drm33.26
Source: linux-2.6
Version: 2.6.32-46
Tags: security
- drm/i915: Attempt to fix watermark setup on 85x (v2)
Prevents a crash launching the X server with 85x cards (aka #661696,
also in 2.6.32.60). Regression introduced in 2.6.32-rc1 (e70236a8d3d0).
- drm/i915: Move Pineview CxSR and watermark code into update_wm hook
- drm/i915: Add CxSR support on Pineview DDR3
For certain cards the driver would set up self-refresh for power
saving but did so incorrectly in external monitor only mode, producing
flicker.
- drm: integer overflow in drm_mode_dirtyfb_ioctl
Integer overflow leading to denial of service or privilege escalation
by users able to use the dirtyfb ioctl (i.e., users in group "video",
CVE-2012-0044). (The current item for CVE-2012-0044 in the Debian
changelog is a typo for CVE-2012-0038.)
Cc-ing Bill in case he'd like to trying the updated package once it's
available to follow up on <http://bugs.debian.org/688564#26>.
Thanks,
Jonathan
