Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> wifi: rsi: fix kthread lifetime race between self-exit and external-stop<br /> <br /> RSI driver use both self-exit(kthread_complete_and_exit) and external-stop<br /> (kthread_stop) when killing a kthread. Generally, kthread_stop() is called<br /> first, and in this case, no particular issues occur.<br /> <br /> However, in rare instances where kthread_complete_and_exit() is called<br /> first and then kthread_stop() is called, a UAF occurs because the kthread<br /> object, which has already exited and been freed, is accessed again.<br /> <br /> Therefore, to prevent this with minimal modification, you must remove<br /> kthread_stop() and change the code to wait until the self-exit operation<br /> is completed.
