- Summary
- [none]
- Details
-
In the tun subsystem in the Linux kernel before 4.13.14, devgetvalidname is not called before registernetdevice. 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.
