CVE-2011-1016

Published: 28 February 2011

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.

From the Ubuntu security team

Marek Olšák discovered that the Radeon GPU drivers did not correctly validate certain registers. On systems with specific hardware, a local attacker could exploit this to write to arbitrary video memory.
