En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cifs: corrige el desbordamiento insuficiente en parse_server_interfaces() En este bucle, recorremos el búfer y después de cada elemento comprobamos si size_left es mayor que el tamaño mínimo que necesitamos. Sin embargo, el problema es que "bytes_left" es del tipo ssize_t mientras que sizeof() es del tipo size_t. Eso significa que debido a la promoción de tipo, la comparación se realiza sin firmar y si nos quedan bytes negativos, el ciclo continúa en lugar de finalizar.
