Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
