Vulnerability from variot

An issue was discovered on OnePlus 7 Pro devices before 10.0.3.GM21BA. The firmware was found to contain functionality that allows a privileged user (root) in the Rich Execution Environment (REE) to obtain bitmap images from the fingerprint sensor because of Leftover Debug Code. The issue is that the Trusted Application (TA) supports an extended number of commands beyond what is needed to implement a fingerprint authentication system compatible with Android. An attacker who is in the position to send commands to the TA (for example, the root user) is able to send a sequence of these commands that will result in the TA sending a raw fingerprint image to the REE. This means that the Trusted Execution Environment (TEE) no longer protects identifiable fingerprint data from the REE. OnePlus 7 Pro The device contains a hard-coded information disclosure vulnerability.Information may be obtained. OnePlus 7 Pro is a smartphone of China OnePlus Technology (OnePlus).

OnePlus 7 Pro 10.0.3.GM21BA has security vulnerabilities in previous versions. Attackers can use this vulnerability to obtain fingerprint images (bitmaps) from the fingerprint sensor
