Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: mctp i2c: maneja dirección de encabezado NULL. daddr puede ser NULL si no hay ninguna entrada presente en la tabla de vecinos, en ese caso el paquete tx debe descartarse. saddr generalmente será configurado por el núcleo MCTP, pero verifica si es NULL en caso de que un paquete sea transmitido por un protocolo diferente.
