GHSA-GC72-PC9P-M8WC
Vulnerability from github – Published: 2024-11-09 12:30 – Updated: 2025-11-04 00:32In 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.
