CVE-2008-2826

Estado: ModificadaMedia (4.9)—

Desbordamiento de entero en la función sctp_getsockopt_local_addrs_old de net/sctp/socket.c en la funcionalidad Stream Control Transmission Protocol (sctp)(Protocolo de Transmisión del Control de Flujo) en el kernel de Linux anterior a 2.6.25.9 permite a usuarios locales provocar una denegación de servicio (agotamiento de recursos y parada de sistema) mediante vectores que involucran un campo addr_num largo en una estructura de datos sctp_getaddrs_old.
