CVE-2026-94952Network attack vector

Memory corruption via port-forwarding parameter overflow

Published Sep 29, 2026 · Updated Sep 29, 2026

A stack-based buffer overflow in TOTOLINK N150RT firmware 3.4.0-B20201030 allows attackers to corrupt memory via port-forwarding requests. During rule addition, the /boafrm/formPortFw handler mishandles the ip_subnet and fw_ip request values, overflowing a stack buffer; the specific copy operation is not publicly documented. TOTOLINK's configuration instructions require a management-interface login, while the available vulnerability description does not establish unauthenticated reachability or a specific post-overflow outcome.
