## Affected

- Huawei Mate 9 Pro: Earlier than LON-L29C 8.0.0.361(C636) versions

## Description

Mate 9 Pro Huawei smartphones earlier than LON-L29C 8.0.0.361(C636) versions have an information leak vulnerability due to the lack of input validation. An attacker tricks the user who has root privilege to install an application on the smart phone, and the application can read some process information, which may cause sensitive information leak.
