CVE-2022-32384Public exploit

Memory corruption via unchecked Wi-Fi setting

Published Jul 1, 2022 · Updated Jul 9, 2026

Stack-based buffer overflow in Tenda AC23 16.03.07.44 allows remote attackers to corrupt memory through a crafted Wi-Fi setting. The formWifiBasicSet handler processes the security_5g parameter without enforcing the destination stack buffer's bounds. No authentication or user interaction is required, but the published vector limits reachability to an adjacent network; the record does not disclose whether corruption causes a crash or code execution.
