In the Linux kernel, the following vulnerability has been resolved:
ath11k: fix netdev open race
Make sure to allocate resources needed before registering the device.
This specifically avoids having a racing open() trigger a BUGON() in modtimer() when ath11kmacopstart() is called before the monreap_timer as been set up.
I did not see this issue with next-20220310, but I hit it on every probe with next-20220511. Perhaps some timing changed in between.
Here's the backtrace:
