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.
