Local privilege escalation via unsafe PendingIntent
Published Mar 30, 2022 · Updated Aug 4, 2024
Local privilege escalation in Google Android 12L allows local users to delete local files through PermissionController. PermissionController uses an unsafe PendingIntent that lets an invoking application perform file deletion with the controller's authority. Exploitation requires user execution privileges but no user interaction, and the published record does not identify the affected function or file paths.
