    Summary:

    Details: In onCreate of DeviceChooserActivity.java, there is a possible way to bypass user consent when pairing a Bluetooth device due to a tapjacking/overlay attack. This could lead to local escalation of privilege and pairing malicious devices with no additional execution privileges needed. User interaction is needed for exploitation.
