Description
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.
Affected configurations
• linux linux kernel (>= 6.14 < 6.18.33)
• linux linux kernel (>= 6.19 < 7.0.10)
