CVE-2024-20020

Estado: ModificadaMedia (4.4)—

En OPTEE, existe una posible escritura fuera de los límites debido a una verificación de los límites incorrecta. Esto podría conducir a la divulgación de información local con privilegios de ejecución de System necesarios. La interacción del usuario no es necesaria para la explotación. ID de parche: ALPS08522504; ID del problema: ALPS08522504.

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).
