Kernel crash via monitor-ring packet-type extraction
Published Dec 8, 2025 · Updated Aug 15, 2026
NULL pointer dereference in Linux kernel 5.18 through 6.1.15 and 6.2 through 6.2.2 allows attackers to crash the kernel. In the ath11k received-MSDU delivery path, monitor-ring packets are incorrectly passed to SKB packet-type extraction despite all being raw, leading ath11k_hw_qcn9074_rx_desc_get_decap_type to dereference a null receive descriptor. Triggering the crash requires a supported Qualcomm 802.11ax device and bringing its interface up in monitor mode; the published trace shows a kernel oops on QCN9074 hardware.
