CVE-2026-9346Network attack vector

Remote memory corruption via submit-url overflow

Published May 24, 2026 · Updated May 24, 2026

Buffer overflow in Edimax EW-7438RPn 1.31 and earlier allows remote attackers to corrupt memory via a crafted submit-url value. The formWirelessTbl handler for /goform/formWirelessTbl processes the submit-url argument without adequate bounds enforcement, causing the overflow. Public details do not establish an authentication requirement or a consequence beyond memory corruption, so code execution and device crash are not confirmed impacts.
