Title
wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifi
Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: Fix invalid data access in ath12k_dp_rx_h_undecap_nwifi In certain cases, hardware might provide packets with a length greater than the maximum native Wi-Fi header length. This can lead to accessing and modifying fields in the header within the ath12k_dp_rx_h_undecap_nwifi function for DP_RX_DECAP_TYPE_NATIVE_WIFI decap type and potentially resulting in invalid data access and memory corruption. Add a sanity check before processing the SKB to prevent invalid data access in the undecap native Wi-Fi function for the DP_RX_DECAP_TYPE_NATIVE_WIFI decap type. Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1

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\u0027s 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 \u2014 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 \u2014 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."
