Information disclosure in Android 13 DevicePolicyManagerService allows local users to read nearby app streaming policy without user interaction. The getNearbyAppStreamingPolicy method returns the policy value without enforcing the READ_NEARBY_STREAMING_POLICY permission. Exploitation requires local code execution but no additional privileges; it exposes policy state without altering it.
