CVE-2025-49495

Estado: AnalizadaAlta (8.4)—

An issue was discovered in the WiFi driver in Samsung Mobile Processor Exynos 1380, 1480, 2400, 1580. Mishandling of an NL80211 vendor command leads to a buffer overflow.

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:L sin UI:R indica acceso local sin interacción (T1068). Buffer overflow en driver WiFi permite ejecución de código arbitrario con privilegios elevados. CWE-120 (buffer copy sin validación) en firmware Samsung.

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.
