CVE-2026-90606Network attack vector

Memory corruption via oversized static_ipv6 parameter

Published Sep 13, 2026 · Updated Sep 13, 2026

Buffer overflow in TOTOLINK A3002MU Hh-B20211125.1046 allows remote attackers to corrupt memory through an IPv6 setup request. The boa formIpv6Setup handler processes the static_ipv6 parameter without enforcing the destination buffer's bounds. The request must reach the router's web management interface; public records do not establish authentication requirements or code execution.
