CVE-2026-92498Hinoki check available

Out-of-bounds reads via unchecked WMI event lengths

Published Sep 17, 2026 · Updated Sep 17, 2026

Buffer overreads in the Linux ath6kl driver allow attackers to trigger out-of-bounds reads via truncated WMI event messages. The ath6kl_wmi_scan_complete_rx(), ath6kl_wmi_addba_req_event_rx(), and ath6kl_wmi_delba_req_event_rx() handlers interpret buffers as event structures without validating their lengths. Reachability requires the driver to process an undersized event; upstream does not establish attacker control, a crash, or data disclosure.
