CVE-2023-38302

Device identifier disclosure via readable system properties

Published Apr 22, 2024 · Updated Mar 27, 2025

Information disclosure in Sharp Rouvo V 1KN0_0_530 allows local users to read Wi-Fi and Bluetooth MAC addresses. A high-privilege process writes the identifiers to the ro.boot.wifi_mac and ro.boot.bt_mac system properties without restricting access. Any local app, including one with no permissions or special privileges, can read the persistent identifiers and use them to track the device indirectly.
