"value": "AV:A - The vulnerable code is the ath12k 802.11 receive path, triggered by a crafted 4-address QoS data frame with the Order bit set that is injected over the air; the attacker must be within Wi-Fi radio range of the target radio. Per kernel guidance, WiFi frame injection is Adjacent.\nAC:L - The attacker fully controls the frame_control field and header contents of the injected frame and can retransmit indefinitely until it lands in the native-Wi-Fi decap or WBM error path; no condition outside the attacker's control is required, and the ath11k twin fix documents real observed stack corruption from this exact path.\nPR:N - No authentication or association is needed — the frame only has to pass the hardware address filter, and the patched null_q_desc/tkip_mic_err error paths specifically handle frames with no peer and no REO queue (ath12k_dp_rx_h_mpdu falls back to HAL_ENCRYPT_TYPE_OPEN when peer lookup fails).\nUI:N - The corruption happens in the NAPI receive path as soon as the frame is processed; no victim action is required beyond having the wireless interface up.\nS:U - The out-of-bounds write corrupts the kernel stack of the receiving host, staying within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The trailing memcpy reads up to 36 bytes from the 30-byte stack array and copies the result into the skb that is delivered to mac80211 (and forwarded in AP/mesh mode), leaking adjacent kernel stack and stale DMA buffer contents; the attacker-controlled stack corruption is further leverageable as a memory-disclosure primitive.\nI:H - Up to 6 bytes of attacker-chosen 802.11 header data are written past a 30-byte stack buffer, overwriting adjacent locals, the stack canary, or saved registers — an out-of-bounds write with controlled content that is a control-flow-hijack primitive.\nA:H - Kernel stack corruption reliably produces a panic via __stack_chk_fail or FORTIFY_SOURCE, and the mishandled skb_pull/skb_push can trigger skb_under_panic; the ath11k report confirms an observed \"Kernel stack is corrupted\" crash."
