Descriptions

Integer signedness error in the drm_modeset_ctl function in (1) drivers/gpu/drm/drm_irq.c in the Direct Rendering Manager (DRM) subsystem in the Linux kernel before 2.6.38 and (2) sys/dev/pci/drm/drm_irq.c in the kernel in OpenBSD before 4.9 allows local users to trigger out-of-bounds write operations, and consequently cause a denial of service (system crash) or possibly have unspecified other impact, via a crafted num_crtcs (aka vb_num) structure member in an ioctl argument.

Error de enteros sin signo en Función drm_modeset_ctl en(1) drivers /gpu/drm/drm_irq.c del subsistema Direct Rendering Manager del kernel de Linux con anterioridad a v2.6.38 y (2) sys/dev/pci/drm/drm_irq.c en el kernel de OpenBSD con anterioridad a v4.9 permite a los usuarios locales provocar una salida de los limites en las operaciones de escritura, y por lo tanto provocar una denegación de servicio ( caída del sistema ) o, posiblemente,tener un impacto no especificado, a través de un miembro de la estructura num_crtcs ( vb_num alias ) manipulado en un argumento ioctl.
