CVE-2026-3290

Estado: Pendiente de análisisAlta (7.4)—

Timing limitations of the HRNG in RS9116 when power save mode is enabled results in predictable values

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, UI:P sugieren interacción del usuario en red adyacente (T1203). CWE-332 (predicción de PRNG) permite derivar claves criptográficas, impactando credenciales (T1212).

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.
