Description
In the Bluetooth Low Energy (BLE) specification, there is a provided example Long Term Key (LTK). If a BLE device were to use this as a hardcoded LTK, it is theoretically possible for a proximate attacker to remotely inject keystrokes on a paired Android host due to improperly used crypto. User interaction is not needed for exploitation. Product: Android. Versions: Android-7.0 Android-7.1.1 Android-7.1.2 Android-8.0 Android-8.1 Android-9. Android ID: A-128843052.
