Description
In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: cancel reset and rc work on device unregister
Both drivers cancelled dump_work on unregister but left reset_work and
rc_work to be flushed only by destroy_workqueue() in mt76_free_device(),
which runs after the hw is unregistered and the hardware stopped. A
reset_work that fires in that window calls ieee80211_restart_hw() and
re-arms mac_work on an unregistered hw, and rc_work touches station state
being torn down. Cancel both up front, alongside dump_work.
