Descriptions

An issue was discovered in ip_ra_control in net/ipv4/ip_sockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of new_ra, which might allow an attacker to cause a denial of service (NULL pointer dereference and system crash). NOTE: this is disputed because new_ra is never used if it is NULL

** EN DISPUTA ** Un problema fue encontrado en la función ip_ra_control en el archivo net/ipv4/ip_sockglue.c en el kernel de Linux hasta la versión 5.1.5. Hay un kmalloc sin marcar de new_ra, que podría permitir a un atacante generar una Denegación de Servicio (desreferencia de puntero NULL y bloqueo del sistema).
NOTA: esto se disputa porque new_ra nunca se usa si es NULL.
