CVE-2019-1999

Estado: ModificadaAlta (7.8)—💥 Exploit

En binder_alloc_free_page en binder_alloc.c, existe una posible doble liberación (double free) debido a un bloqueo incorrecto. Esto podría llevar a un escalado de privilegios local en el kernel sin necesitar privilegios de ejecución adicionales. No se necesita interacción del usuario para explotarlo. Producto: Android. Versiones: Android kernel. Android ID: A-120025196.

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.
