NotificationSoundPreference.onActivityResult accepted a ringtone content URI and passed it for playback without verifying that its source user belonged to the current user’s profile group. A local user with ordinary execution privileges can cross a device user boundary; no user interaction is required, and the reported impact is audio disclosure only.
