CVE-2025-40352

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The mlxbf pmc driver in the Linux kernel does not call sysfs attr init() during the initialization of the "count clock" data structure. This causes a warning related to lock-related debug logic (CONFIG LOCK STAT) when a BlueField-3 SOC is booted, specifically a "BUG: key has not been registered!" warning. The issue occurs due to missing initialization within the mlxbf pmc probe function.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
