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

Description A flaw exists in the Linux kernel’s perf/smmuv3 component related to a hotplug callback leak within the arm smmu pmu init() function. Specifically, the function fails to remove a callback added by cpuhp setup state multi() when platform driver register() fails. This results in a memory leak. The issue is similar to a previously addressed problem in arm ccn init().

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