Descriptions

The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.

El kernel de Linux versiones 2.6.0 hasta 2.6.30.4 y 2.4.4 hasta 2.4.37.4, no inicia todos los punteros de función para operaciones de socket en estructuras de proto_ops, lo que permite a los usuarios locales activar una desreferencia de puntero NULL y alcanzar privilegios mediante el uso de mmap que asigna la página cero, inserta el código arbitrario en esta página y luego invoca una operación no disponible, como es demostrado por la operación de sendpage (función sock_sendpage) en un socket PF_PPPOX.
