This is host IPC, not WiFi frame processing, so Adjacent/Network do not apply.\nAC:L - The attacker only needs to send a QMI indication/request with a msg_id absent from ath11k_qmi_msg_handlers[]; the missing null terminator makes the OOB walk deterministic. Discovering the client port (ephemeral QRTR range) is fully under attacker control.\nPR:L - AF_QIPCRTR sockets can be created and bound to ephemeral ports without privileges; no CAP_NET_ADMIN is required to send to another local QRTR port. Real root is not required.\nUI:N - Exploitation is a direct local send to the ath11k QMI socket; no victim action is required.\nS:U - Impact is confined to the host kernel's memory/control-flow integrity; there is no VM/IOMMU/security-authority boundary crossing.\nC:H - qmi_invoke_handler() performs an unbounded out-of-bounds read of adjacent kernel memory while scanning for a handler, and a crafted type/msg_id can select a false adjacent handler entry, enabling further disclosure primitives.\nI:H - Matching an out-of-bounds handler descriptor can invoke a garbage function pointer and/or run qmi_decode_message() with attacker-influenced ei/decoded_size, yielding memory corruption and control-flow hijack potential.\nA:H - The same path can soft-lock in an unbounded scan, oops on unmapped access, or crash when a bogus handler is invoked, as confirmed by the sibling ath12k KASAN global-OOB report for the identical terminator bug."
