CVE-2025-7213

Estado: AplazadaMedia (4.5)—

A vulnerability classified as critical has been found in FNKvision FNK-GU2 up to 40.1.7. Affected is an unknown function of the component UART Interface. The manipulation leads to on-chip debug and test interface with improper access control. It is possible to launch the attack on the physical device. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
