Description

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: Fix possible NULL pointer dereference in mt7996_mac_write_txwi_80211() For injected frames (e.g. via radiotap), mac80211 can pass info->control.vif = NULL, as explicitly noted in struct ieee80211_tx_info.
