kernel/bpf/verifier.c en el kernel de Linux, en versiones 4.9.x hasta la 4.9.71, no verifica la relación entre los valores de punteros y la pila BPF, lo que permite que los usuarios locales provoquen una denegación de servicio (desbordamiento de enteros o acceso a la memoria no válido) o, posiblemente, causar otros impactos no especificados.
