{"schema":"threatline.record/2","record":{"id":"CVE-2026-97442","aliases":[],"summary":"wifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: ath11k: fix invalid data access in ath11k_dp_rx_h_undecap_nwifi\n\nIn certain cases, hardware might provide packets with a\nlength greater than the maximum native Wi-Fi header length.\nThis can lead to accessing and modifying fields in the header\nwithin the ath11k_dp_rx_h_undecap_nwifi() function for the\nDP_RX_DECAP_TYPE_NATIVE_WIFI decap type and\npotentially result in invalid data access and memory corruption.\n\nKernel stack is corrupted in: ath11k_dp_rx_h_undecap+0x6b0/0x6b0 [ath11k]\nCall trace:\n ath11k_dp_rx_h_mpdu+0x0/0x2e8 [ath11k]\n ath11k_dp_rx_h_mpdu+0x1e0/0x2e8 [ath11k]\n ath11k_dp_rx_wbm_err+0x1e0/0x450 [ath11k]\n ath11k_dp_rx_process_wbm_err+0x2fc/0x460 [ath11k]\n ath11k_dp_service_srng+0x2e0/0x348 [ath11k]\n\nAdd a sanity check before processing the SKB to prevent invalid\ndata access in the undecap native Wi-Fi function for the\nDP_RX_DECAP_TYPE_NATIVE_WIFI decap type.\n\nThis adapted from the discussion/patch of the ath12k driver [1].\n\nTested-on: WCN6855 hw2.1 PCI WLAN.HSP.1.1-04685-QCAHSPSWPL_V1_V2_SILICONZ_IOE-1","categories":["Operating
