What it is

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.

Check vif pointer before executing ieee80211_vif_is_mld() in

mt7996_mac_write_txwi_80211 routine in order to avoid a possible NULL

pointer dereference.
