Summary
Starting an Unnoticed ForegroundService by Providing Malformed Notification Extra

In enqueueNotificationInternal of NotificationManagerService.java, there is a possible way to run a foreground service without showing a notification due to improper input validation. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
