CVE-2010-2962

Publication date 26 November 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

drivers/gpu/drm/i915/i915_gem.c in the Graphics Execution Manager (GEM) in the Intel i915 driver in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.36 does not properly validate pointers to blocks of memory, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via crafted use of the ioctl interface, related to (1) pwrite and (2) pread operations.

From the Ubuntu Security Team

Kees Cook discovered that the Intel i915 graphics driver did not correctly validate memory regions. A local attacker with access to the video card could read and write arbitrary kernel memory to gain root privileges.

Notes

kees

jaunty's code is a bit different, but at least half looks to still apply.
