CVE-2023-40111

Local privilege escalation via activity-targeting PendingIntent

Published Feb 15, 2024 · Updated Mar 28, 2025

Privilege escalation in Google Android 14 allows local users to launch an activity with system_server authority through a media button receiver. MediaSessionRecord.setMediaButtonReceiver accepts a PendingIntent targeting an activity and later sends it as system_server, bypassing background activity launch restrictions. Exploitation requires user interaction; a malicious app can cause an otherwise prohibited activity launch with system privileges.
