In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: fix deadlock in remain-on-channel
mt76 remain on channel() and mt76 roc complete() call mt76 set channel()
while already holding dev->mutex. Since mt76 set channel() also acquires
dev->mutex, this results in a deadlock.
Use mt76 set channel() instead of mt76 set channel().
Add cancel delayed work sync() for mac work before acquiring the mutex
in mt76 remain on channel() to prevent a secondary deadlock with the
mac work workqueue.
