CVE-2025-57215Public exploitNetwork attack vector

Unauthenticated service crash via oversized deviceId

Published Aug 28, 2025 · Updated Aug 28, 2025

Stack-based buffer overflow in Tenda AC10 v4.0 firmware 16.03.10.20 allows remote attackers to crash the router via a crafted request. The get_parentControl_list_Info function processes an oversized deviceId parameter without enforcing the destination buffer bounds, overwriting stack memory. No authentication or user interaction is required, and the documented consequence is service interruption rather than data access or modification.
