Descriptions
In the Linux kernel before 5.0, a memory leak exists in sit_init_net() in net/ipv6/sit.c when register_netdev() fails to register sitn->fb_tunnel_dev, which may cause denial of service, aka CID-07f12b26e21a.
En el kernel de Linux versiones anteriores a 5.0, se presenta una pérdida de memoria en la función sit_init_net() en el archivo net/ipv6/sit.c cuando la función register_netdev() no puede registrar sitn-)fb_tunnel_dev, lo que puede causar una denegación de servicio, también se conoce como CID-07f12b26e21a.
A flaw was found in the way the sit_init_net function in the Linux kernel handled resource cleanup on errors. This flaw allows an attacker to use the error conditions to crash the system.
