Vulnerability from fkie_nvd - Published: 2026-05-28 10:16 - Updated: 2026-06-17 10:53
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
wifi: rsi: fix kthread lifetime race between self-exit and external-stop
RSI driver use both self-exit(kthread_complete_and_exit) and external-stop
(kthread_stop) when killing a kthread. Generally, kthread_stop() is called
first, and in this case, no particular issues occur.
However, in rare instances where kthread_complete_and_exit() is called
first and then kthread_stop() is called, a UAF occurs because the kthread
object, which has already exited and been freed, is accessed again.
Therefore, to prevent this with minimal modification, you must remove
kthread_stop() and change the code to wait until the self-exit operation
is completed.
