CVE-2022-50820

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

Description A flaw exists in the Linux kernel’s dmc620 pmu init() function within the perf/arm dmc620 module. The function fails to remove a callback added by cpuhp setup state multi() when platform driver register() fails, leading to a hotplug callback leak. This 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.
