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 BUG_ON() in
mod_timer() when ath11k_mac_op_start() is called before the
mon_reap_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.
