  "summary": "wifi: rsi: fix kthread lifetime race between self-exit and external-stop",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rsi: fix kthread lifetime race between self-exit and external-stop\n\nRSI driver use both self-exit(kthread_complete_and_exit) and external-stop\n(kthread_stop) when killing a kthread. Generally, kthread_stop() is called\nfirst, and in this case, no particular issues occur.\n\nHowever, in rare instances where kthread_complete_and_exit() is called\nfirst and then kthread_stop() is called, a UAF occurs because the kthread\nobject, which has already exited and been freed, is accessed again.\n\nTherefore, to prevent this with minimal modification, you must remove\nkthread_stop() and change the code to wait until the self-exit operation\nis completed.",
