CVE-2025-8832

Estado: AnalizadaAlta (7.4)—

A vulnerability was determined in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. This vulnerability affects the function setDMZ of the file /goform/setDMZ. The manipulation of the argument DMZIPAddress leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
