The vulnerability was disclosed on February 10, 2021, affecting Android versions 8.1, 9, 10, and 11. This security flaw allows unauthorized access to Bluetooth scan results due to a missing permission check (NVD, CVE).

Technical details

Exploitability

The vulnerability can be exploited without requiring any additional execution privileges or user interaction. This makes it particularly concerning as it can be leveraged by an attacker with minimal prerequisites (CVE).
