CVE-2020-0121

Local location disclosure via AppOpsService permission bypass

Published Jun 10, 2020 · Updated Aug 4, 2024

Information disclosure in Android 10 allows local users to access location data via a permission bypass in AppOpsService. The updateUidProcState method in AppOpsService.java contains a logic error that bypasses an intended permission decision when processing UID state. Exploitation requires a local application running with user-level execution privileges and no user interaction; the documented consequence is location-data disclosure without integrity or availability impact.
