Due to insufficient parameters verification GPU driver of Mate 9 Pro Huawei smart phones with the versions before LON-AL00B 8.0.0.356(C00) has an arbitrary memory free vulnerability. An attacker can tricks a user into installing a malicious application on the smart phone, and send given parameter to driver to release special kernel memory resource. Successful exploit may result in phone crash or arbitrary code execution.

Huawei Mate 9 Pro smartphones with software of LON-AL00BC00B139D, LON-AL00BC00B229, LON-L29DC721B188 have a memory double free vulnerability. The system does not manage the memory properly, that frees on the same memory address twice. An attacker tricks the user who has root privilege to install a crafted application, successful exploit could result in malicious code execution.

The GPU driver of Mate 9 Huawei smart phones with software before MHA-AL00B 8.0.0.334(C00) and Mate 9 Pro Huawei smart phones with software before LON-AL00B 8.0.0.334(C00) has a memory double free vulnerability. An attacker tricks a user into installing a malicious application, and the application can call special API, which triggers double free and causes a system crash or arbitrary code execution.
