GHSA-P54Q-624C-FR42

Vulnerability from github – Published: 2022-05-24 21:59 – Updated: 2022-05-24 21:59

Details

In the tun subsystem in the Linux kernel before 4.13.14, dev_get_valid_name is not called before register_netdevice. This allows local users to cause a denial of service (NULL pointer dereference and panic) via an ioctl(TUNSETIFF) call with a dev name containing a / character. This is similar to CVE-2013-4343.
