      "value": "Kernel software from a non-secure operating system on a platform with Trusted Execution Environment support, may cause GPU Firmware to boot up using data from non-secure memory.\n\n\n\nThe GPU thread of control (Firmware) uses a pointer from non-secure memory belonging to the Rich Execution Environment (REE) when saving or retrieving internal data between the tightly coupled private memory to main memory. An attacker with control over the REE kernel may modify the pointer value, corrupting the data used by the GPU Firmware."

      "value": "El software del kernel de un sistema operativo no seguro en una plataforma con soporte para Entorno de Ejecución Confiable, puede hacer que el firmware de la GPU arranque utilizando datos de memoria no segura.\n\nEl hilo de control de la GPU (firmware) utiliza un puntero de memoria no segura perteneciente al Entorno de Ejecución Enriquecido (REE) al guardar o recuperar datos internos entre la memoria privada estrechamente acoplada y la memoria principal. Un atacante con control sobre el kernel del REE puede modificar el valor del puntero, corrompiendo los datos utilizados por el firmware de la GPU."
