Descriptions

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.

drivers/gpu/drm/i915/i915_gem.c en el Graphics Execution Manager (GEM) en el controlador Intel i915 en el subsistema Direct Rendering Manager (DRM) en el kernel de Linux anterior a v2.6.36 no valida correctamente los punteros a los bloques de la memoria, lo cual permite a usuarios locales escribir en ubicaciones de memoria del núcleo a su elección, y por consiguiente obtener privilegios, mediante el uso de la interfaz ioctl manipulada, relacionado con (1) pwrite y (2) operaciones pread.
