A vulnerability was found in Linux Kernel 2.6.16.9 (Operating System) and classified as critical. This issue affects an unknown code. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:
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.
The issue has been introduced in 03/20/2006. The weakness was published 11/26/2010 by Kees Cook as Bug 637688 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com. The identification of this vulnerability is CVE-2010-2962. The exploitation is known to be easy. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. The technical details are unknown and an exploit is not publicly available.
