CVE-2025-20700

Estado: AplazadaAlta (8.8)—

In the Airoha Bluetooth audio SDK, there is a possible permission bypass that allows access critical data of RACE protocol through Bluetooth LE GATT service. This could lead to remote escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:A indica red adyacente; acceso GATT sin privilegios permite bypassear permisos y escalar privilegios (PR:N). Impacto de acceso a cuenta (T1078) por compromiso de protocolo RACE; escalada de privilegios (T1068) confirmada por 'remote escalation of privilege'.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
