A memory leak problem was found in the TCP source port generation algorithm in net/ipv4/tcp.c due to the small table perturb size. This flaw may allow an attacker to information leak and may cause a denial of service problem.
Se ha encontrado un problema de pérdida de memoria en el algoritmo de generación de puertos de origen TCP en el archivo net/ipv4/tcp.c debido al pequeño tamaño de la tabla de perturbación. Este fallo puede permitir a un atacante un filtrado de información y puede causar un problema de denegación de servicio
