CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's mt76 driver, specifically in the mt7996_mac_write_txwi_80211 function, where a NULL pointer dereference can occur due to improper handling of injected frames. This flaw could potentially lead to system crashes or instability when processing certain network traffic. Organizations using affected Linux distributions should prioritize this fix to maintain system reliability and security.
Original NVD 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. 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.
