CVE-2025-15216Public exploitNetwork attack vector

Authenticated memory corruption via unchecked bindnum handling

Published Dec 30, 2025 · Updated Dec 30, 2025

Stack-based buffer overflow in Tenda AC23 16.03.07.52 allows remote authenticated users to corrupt memory via a crafted bindnum value. The fromSetIpMacBind handler for /goform/SetIpMacBind accepts bindnum from the request body without enforcing the destination stack buffer's capacity. Low-privileged management access is required, and the established consequence is memory corruption; code execution is not established.
