"value": "AV:A - The vulnerable path is the mt7996 WiFi 7 TX handler, driven by frames the driver generates in response to an over-the-air MLO association from a wireless peer. Per kernel CNA guidance WiFi-reachable bugs are Adjacent.\nAC:L - `IEEE80211_LINK_UNSPECIFIED` is mac80211's default link value for every MLD-addressed frame and every fast-xmit frame, so an attacker simply associating with multi-link and prompting any management/action/EAPOL frame reliably drives the index-15 access. No race, timing, or memory-layout condition outside the attacker's control is involved.\nPR:N - The frames that carry `link_id == IEEE80211_LINK_UNSPECIFIED` include control-port/EAPOL and management frames emitted during MLO association, before the peer is authorized; on open networks no credentials exist at all. No account or capability on the target system is needed.\nUI:N - The AP transmits the offending frames automatically as part of normal MLO association and link management. No action by any local user or administrator is required.\nS:U - The out-of-bounds access and the resulting corruption are confined to the kernel of the affected device; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The out-of-bounds read walks past `link[]` into adjacent struct members and, on the vif path, substitutes `offchannel_link` so frames are transmitted under the wrong wcid/WTBL security context, exposing frame contents with the wrong or absent key. Combined with the memory-safety violation feeding a dereferenced pointer, High is the defensible assessment.\nI:H - The OOB-derived `wcid` pointer is used for writes in `mt76_tx()` — `__skb_queue_tail()` into `wcid->tx_pending` and `list_add_tail(&wcid->tx_list, &phy->tx_list)` — so kernel memory is modified through an out-of-bounds-sourced pointer, and the vif path additionally misdirects frames onto the wrong link/peer.\nA:H - Dereferencing the bogus link pointer in `mt76_tx()` faults in the TX path (frequently in softirq context), producing a kernel oops/panic on the AP or client and taking down the wireless device and typically the whole system."
