Estado: ModificadaCrítica (9.8)—💥 PoC

Se descubrió un problema en los dispositivos móviles LG con software Android OS 7.2, 8.0, 8.1, 9 y 10. La ejecución de código arbitrario puede ocurrir a través del gestor de arranque debido a una vulnerabilidad de arranque en frío EL1 / EL3 que involucra recursos raw_. La identificación de LG es LVE-SMP-200006 (mayo de 2020).

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
