Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: do not run mt76_unregister_device() on unregistered hw Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211_register_hw hasn't been called. When removing the driver, ieee802111_unregister_hw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76_unregister_device routine just for registered hw.

Al intentar sondear una tarjeta PCI mt7921e sin firmware, se obtiene un sondeo exitoso donde no se ha llamado a ieee80211_register_hw. Al desinstalar el controlador, se llama a ieee802111_unregister_hw incondicionalmente, lo que provoca una desreferencia de puntero nulo en el kernel. Se solucion\u00f3 el problema al ejecutar la rutina mt76_unregister_device solo para hardware registrado."
