Description

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.

Affected configurations

• linux linux kernel (>= 5.18 < 6.1.113) • linux linux kernel (>= 6.2 < 6.2.9) • linux linux kernel 6.3
