The code use core->sys_err_done to make sync work.The core->work is started in venus_event_notify.If we call venus_remove, there might be an unfished work. The possiblesequence is as follows:CPU0 CPU1 |venus_sys_error_handlervenus_remove |hfi_destroy |venus_hfi_destroy |kfree(hdev); | |hfi_reinit |venus_hfi_queues_reinit |//use hdevFix it by canceling the work in venus_remove. ### POC #### Reference No PoCs from references. #### Github - https://github.com/w4zu/Debian_security
