CVE-2026-34856

Estado: AnalizadaAlta (7.5)—

UAF vulnerability in the communication module. Impact: Successful exploitation of this vulnerability may affect availability.

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.

Vulnerabilidad de red sin autenticación (AV:N/PR:N) en módulo de comunicación de HarmonyOS. UAF remoto causa DoS (A:H). T1190 por acceso red sin privilegios; T1499.004 por impacto de disponibilidad en servicio remoto.

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.
