About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
perf/arm_dmc620: Fix hotplug callback leak in dmc620_pmu_init()
dmc620_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.
