In the Linux kernel, the following vulnerability has been resolved:
perf/armdmc620: Fix hotplug callback leak in dmc620pmu_init()
dmc620pmuinit() won't remove the callback added by cpuhpsetupstatemulti() when platformdriverregister() failed. Remove the callback by cpuhpremovemultistate() in fail path.
Similar to the handling of armccninit() in commit 26242b330093 ("bus: arm-ccn: Prevent hotplug callback leak")
