CVE-2019-15666

Estado: ModificadaMedia (4.4)—

Se descubrió un fallo en el núcleo de Linux en versiones anteriores a 5.0.19. Hay un acceso a array fuera de límites en __xfrm_policy_unlink, lo que causará una denegación del servicio, ya que verify_newpolicy_info en net/xfrm/xfrm_user.c gestiona mal la validación de directorios.
