kernel: memory leak in register_queue_kobjects() in net/core/net-sysfs.c leads to denial of service

A flaw that allowed an attacker to leak kernel memory was found in the network subsystem where an attacker with permissions to create tun/tap devices can create a denial of service and panic the system...

The vulnerability of the dev_get_valid_name function in the TUN subsystem of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the devgetvalidname function in the TUN subsystem of the Linux operating system is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...
