In the Linux kernel, the following vulnerability has been resolved:
perf/smmuv3: Fix hotplug callback leak in arm_smmu_pmu_init()
arm_smmu_pmu_init() won't remove the callback added by cpuhp_setup_state_multi() when platform_driver_register() failed. Remove the callback by cpuhp_remove_multi_state() in fail path.
Similar to the handling of arm_ccn_init() in commit 26242b330093 ("bus: arm-ccn: Prevent hotplug callback leak")
