What is CVE-2019-5306?

A security vulnerability exists in Huawei P20 smartphones that allows attackers to bypass the Factory Reset Protection (FRP) feature. This can be exploited when a device is reconfigured via the FRP mechanism. An unauthorized user can execute a specific sequence of actions that leads to the deletion of the activation lock, effectively circumventing the FRP. This leaves the device vulnerable to unauthorized access, compromising the security of personal information stored on it.
