How to fix?

Upgrade SLES:15.4 kernel-default-base to version 5.14.21-150400.24.144.1.150400.24.70.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-default-base package and not the kernel-default-base package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write()

This was found by a static analyzer. We should not forget the trailing zero after copy_from_user() if we will further do some string operations, sscanf() in this case. Adding a trailing zero will ensure that the function performs properly.
