CVE-2024-34719

Local privilege escalation via null attribution source

Published Nov 13, 2024 · Updated Dec 4, 2024

Permission bypass in Android 12, 12L, 13, and 14 allows local users to elevate privileges through Bluetooth Binder calls. Several Bluetooth permission checks in Utils.java accept a null AttributionSource, creating a stub attribution chain that checks Bluetooth permissions instead of the calling app's permissions. A malicious local app needs no user interaction or additional execution privileges to invoke affected Binder methods and act with permissions it does not hold.
