CVE-2025-8178Public exploitNetwork attack vector

Authenticated memory corruption via device1D heap overflow

Published Jul 26, 2025 · Updated Jul 28, 2025

Heap-based buffer overflow in Tenda AC10 16.03.10.13 allows remote authenticated users to corrupt memory via a crafted device1D value. The RequestsProcessLaid web handler mishandles the device1D request-body value so processing writes beyond a heap buffer. Low-privilege access is required; triggering the flaw can corrupt router memory and interrupt service, while code execution is not publicly demonstrated.
