CVE-2018-7191 [MEDIUM] CWE-400 kernel: denial of service via ioctl call in network tun handling
kernel: denial of service via ioctl call in network tun handling
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.
A flaw was found in the Linux kernel's implementation of networking tunnel device ioctl. A local attacker can cause a denial of service (NULL pointer dereference and panic) via an ioctl (TUNSETIFF) call with a dev name containing a / character.
Package: kernel (Red Hat Enterprise Linux 5) - Out of support scope
