CVE-2025-8816
Estado: AnalizadaAlta (7.4)—
A vulnerability was determined in Linksys RE6250, RE6300, RE6350, RE6500, RE7000 and RE9000 up to 20250801. Affected is the function setOpMode of the file /goform/setOpMode. The manipulation of the argument ethConv leads to stack-based buffer overflow. It is possible to launch the attack 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.
