CVE-2023-20994

Estado: ModificadaMedia (6.7)—

En _ufdt_output_property_to_fdt de ufdt_convert.c, existe una posible escritura fuera de límites debido a una comprobación de límites incorrecta. Esto podría dar lugar a una escalada de privilegios local con necesidad de privilegios de ejecución del sistema. No se necesita interacción del usuario para la explotación.Product: AndroidVersions: Android-13Android ID: A-259062118
