CVE-2021-1011

Local information disclosure via missing permission check

Published Dec 15, 2021 · Updated Aug 3, 2024

Information disclosure in Android 12 allows local users to read package state via setPackageStoppedState without a permission check. PackageManagerService fails to authorize this operation before changing or exposing stopped-state data for a package. Exploitation requires local code execution on the device but no additional privileges or user interaction, and the consequence is information disclosure without integrity or availability impact.
