Details
In the Linux kernel, the following vulnerability has been resolved:
media: venus: fix use after free bug in venus_remove due to race condition
in venus_probe, core->work is bound with venus_sys_error_handler, which is used to handle error. 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 possible sequence is as follows:
CPU0 CPU1
|venus_sys_error_handler
venus_remove | hfi_destroy | venus_hfi_destroy | kfree(hdev); | |hfi_reinit |venus_hfi_queues_reinit |//use hdev
Fix it by canceling the work in venus_remove.
