CVE-2022-20286

Local privilege escalation via background activity bypass

Published Aug 11, 2022 · Updated Aug 3, 2024

Privilege escalation in Android 13 Connectivity allows local users to start activities from the background despite platform restrictions. An undisclosed logic error in Connectivity incorrectly bypasses the background activity-start restriction when a user-privileged process requests an activity launch. A local process with User execution privileges can trigger the bypass without user interaction; Google has not published the affected function or condition.
