CVE-2022-50820 is a vulnerability of currently unknown severity. 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. Similar to the handling of arm_ccn_init() in commit 26242b330093 ("bus: arm-ccn: Prevent hotplug callback leak"). EPSS estimates a 0.20% chance of exploitation in the next 30 days.
