Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: unwind state on add_interface failure When mt76_wcid_alloc() fails, mt7915_add_interface() returned without clearing the vif_mask/omac_mask bits it had already set, without removing the firmware dev info added earlier, and without clearing a monitor_vif pointer to the vif mac80211 is about to free. mac80211 does not call remove_interface() for a failed add, so the indices and firmware dev entry leaked permanently and testmode could dereference the stale monitor_vif. Add a proper error unwind.
