CVE-2021-0583

Local privilege escalation via Bluetooth dialog tapjacking

Published Oct 11, 2021 · Updated Aug 3, 2024

Tapjacking in AAOS CarSettings in Google Android Automotive OS 9 and 10 allows local users to enable Bluetooth without consent. Google identifies BluetoothPairingDialog.onCreate as the locus but does not disclose the exact missing overlay check; an overlay redirects the required tap to enable Bluetooth. Exploitation requires user-level code and user interaction on the device; the bounded result is unauthorized Bluetooth activation and local privilege escalation.
