Lock-Screen Bypass Vulnerability in Huawei P9 Smartphones

CVE-2017-2691

Summary

The Huawei P9 smartphones are susceptible to a lock-screen bypass vulnerability that allows unauthorized users to access the device. This flaw enables an unauthenticated attacker to force the phone into fastboot mode. During this process, the attacker can delete the user's password file, thereby circumventing the screen lock requirement. After the device reboots, the attacker can gain access to the phone without needing to enter the screen lock password, compromising user data and privacy.
