CVE-2017-7558

Estado: ModificadaAlta (7.5)—

Se ha encontrado una fuga de datos del kernel debido a una lectura fuera de límites en el kernel de Linux en las funciones inet_diag_msg_sctp{,l}addr_fill() y sctp_get_sctp_info() presentes desde la versión 4.7-rc1 hasta la versión 4.13. Ocurre una fuga de datos cuando estas funciones rellenan las estructuras de datos sockaddr utilizadas para exportar la información de diagnóstico del socket. Como resultado, se podían filtrar hasta 100 bytes de los datos de la slab a un espacio de usuario.
