CVE-2025-14739

Root code execution via uninitialized SUBSCRIBE pointer

Published Dec 18, 2025 · Updated Dec 18, 2025

Uninitialized pointer access in TP-Link WR940N and WR941ND firmware allows local users to crash the router or execute root code. The UPnP/SOAP SUBSCRIBE request path uses a pointer before initializing it, so crafted requests can drive an invalid access in the router process. Local-network access and no credentials are required; affected releases are WR940N v5 3.20.1 Build 200316 and earlier and WR941ND v6 3.16.9 Build 151203 and earlier.
