CVE-2009-3725

Estado: ModificadaAlta (7.2)—

La capa de conector en el kernel Linux versiones anteriores a v2.6.31.5 no requiere de la capacidad CAP_SYS_ADMIN para ciertas interacciones de los subsistemas (1) uvesafb, (2) pohmelfs, (3) dst, o (4) dm, permitiendo a usuarios locales saltar las restricciones de acceso implementadas y obtener privilegios mediante peticiones a las funciones en esos subsistemas.
