https://notcve.org/view.php?id=CVE-2022-44455
The appspawn and nwebspawn services within OpenHarmony-v3.1.2 and prior versions were found to be vulnerable to buffer overflow vulnerability due to insufficient input validation. An unprivileged malicious application would be able to gain code execution within any application installed on the device or cause application crash. Se descubrió que los servicios appspawn y nwebspawn dentro de OpenHarmony-v3.1.2 y versiones anteriores eran vulnerables a la vulnerabilidad de desbordamiento de búfer debido a una validación de entrada insuficiente. Una aplicación maliciosa sin privilegios podría obtener la ejecución de código dentro de cualquier aplicación instalada en el dispositivo o provocar el bloqueo de la aplicación. • https://gitee.com/openharmony/security/blob/master/en/security-disclosure/2022/2022-12.md • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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.

OpenHarmony-v3.1.2 and prior versions, 3.0.6 and prior versions have an Out-of-bound memory read and write vulnerability in /dev/mmz_userdev device driver. The impact depends on the privileges of the attacker. The unprivileged process run on the device could read out-of-bound memory leading sensitive to information disclosure. The processes with system user UID run on the device would be able to write out-of-bound memory which could lead to unspecified memory corruption.
