CVE-2026-28634

Estado: AnalizadaAlta (7.8)—

In handleUssdRequest of PhoneInterfaceManager.java, there is a possible way to send a USSD request without permission due to a logic error in the code. This could lead to local 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.

Escalada de privilegios local en Android (AV:L, PR:L) por error lógico sin interacción del usuario. Acceso a funcionalidad USSD protegida permite suplantación de identidad y obtención de permisos elevados.

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.
