CVE-2020-0009

Estado: ModificadaMedia (5.5)—💥 Exploit

En la función calc_vm_may_flags del archivo ashmem.c, hay una posible escritura arbitraria en la memoria compartida debido a una omisión de permisos. Esto podría conllevar a una escalada local de privilegios mediante la corrupción de la memoria compartida entre procesos, sin ser necesarios privilegios de ejecución adicionales. No es requerida una interacción del usuario para su explotación. Producto: Android, Versiones: kernel de Android, ID de Android: A-142938932

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.
