En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:

drm/nouveau: Corrige una fuga de referencia de GEM en validate_init()

En las rutas de error de ttm_bo_reserve() y de "vma not found", el bucle se interrumpe sin añadir el objeto buscado a ninguna lista de validación, por lo que la referencia obtenida mediante drm_gem_object_lookup() nunca se libera; validate_fini() solo recorre las listas unidas. Libera la referencia antes de interrumpir el bucle en ambas rutas.
