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.
