CVE-2010-2962

Description

From CVE.org

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.

Statement

The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4, 5, and Red Hat Enterprise MRG did not include support for Graphics Execution Manager (GEM) in the i915 driver, and therefore are not affected by this issue.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
