CVE-2026-74322 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
