How to fix?

Upgrade SLES:15.0 reiserfs-kmp-default to version 4.12.14-150.22.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream reiserfs-kmp-default package and not the reiserfs-kmp-default package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

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.
