CVE-2025-57057Network attack vector

Unauthenticated device crash via listStr overflow

Published Sep 9, 2025 · Updated Sep 10, 2025

Stack-based overflow in Tenda G3 firmware 3.0br_V15.11.0.17 allows remote attackers to crash the device via a crafted request. Public records identify listStr as overflowing a stack buffer in ipMacBindListStore but do not disclose the specific copy operation or missing bound. A network request reaches the function without authentication or user interaction, and the documented consequence is service interruption rather than data exposure or code execution.
