CVE-2022-20193

Local privilege escalation via permission attribution conflation

Published Jun 15, 2022 · Updated Aug 3, 2024

Privilege escalation in Android 12L Framework allows local users to gain elevated access through incorrect permission attribution. PermissionUsageHelper.getUniqueUsagesWithLabels conflates distinct apps while aggregating permission-use labels, causing permission activity to be attributed to the wrong app. Exploitation requires low-privileged local access and user interaction; successful exploitation elevates the attacker's privileges.
