      "value": "OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have a Kernel memory pool override vulnerability in /dev/mmz_userdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could disclose sensitive information including kernel pointer, which could be used in further attacks. The processes with system user UID run on the device would be able to mmap memory pools used by kernel and override them which could be used to gain kernel code execution on the device, gain root privileges, or cause device reboot."

El impacto depende de los privilegios del atacante. El proceso no privilegiado que sea ejecutado en el dispositivo podr\u00eda divulgar informaci\u00f3n confidencial, incluyendo el puntero del kernel, que podr\u00eda ser usado en otros ataques. Los procesos con UID de usuario del sistema que es ejecutado en el dispositivo podr\u00edan mmap pools de memoria usados por el kernel y anularlos, lo que podr\u00eda usarse para obtener una ejecuci\u00f3n de c\u00f3digo del kernel en el dispositivo, obtener privilegios de root o causar el reinicio del dispositivo"
