Name of the Vulnerable Software and Affected Versions Android versions 8.0 through 10

Description A permissions bypass issue exists due to a missing permission check in the onCommand method of CompanionDeviceManagerService.java. This could lead to local escalation of privilege, allowing background data usage or launching from the background without requiring additional execution privileges. User interaction is not needed for exploitation.
