Lifecycle Timeline
7DescriptionCVE.org
In writeToParcel of BleRssiRangingCapabilities.java, there is a possible way to obtain the Bluetooth MAC address due to a missing permission check. This could lead to local information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Local information disclosure in Android 16 and 17 exposes the device Bluetooth MAC address through a missing permission check in the writeToParcel method of BleRssiRangingCapabilities.java. Any low-privileged local application can invoke this code path without holding the required Bluetooth permission, silently retrieving a hardware identifier that can be used to track a device across networks. …
