CVE-2022-50319

Medium

In the Linux kernel, the following vulnerability has been resolved: coresight: trbe: remove cpuhp instance node before remove cpuhp state cpuhp_state_add_instance() and cpuhp_state_remove_instance() should be used in pairs. Or there will lead to the warn on cpuhp_remove_multi_state() since the cpuhp_step list is not empty. The following is the error log with 'rmmod coresight-trbe': Error: Removing state 215 which has instances left.
