CVE-2025-57086Network attack vector

Unauthenticated service interruption via formDeleteMeshNode overflow

Published Sep 9, 2025 · Updated Sep 9, 2025

Stack overflow in Tenda W30E firmware 16.01.0.19 (5037) allows remote attackers to interrupt service via a crafted request. The public record identifies formDeleteMeshNode and its String input but does not disclose the exact unchecked copy or fixed-size destination that overflows. No authentication or user interaction is required, and the documented consequence is limited to service interruption rather than data access or modification.
