Answer in brief
CVE-2026-74322 records a Unknown severity vulnerability in wifi: mt76: mt7996: Fix possible NULL pointer dereference in mt7996_mac_write_txwi_80211(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
