What does the GTW_w081_udsMessageRejected alert mean?

Due to product security concerns, the vehicle gateway (GTW) has blocked a unified diagnostic services (UDS) message that the infotainment system attempted to send via GTW over a controller area network (CAN) bus. May result from a UDS message not having correct permissions (not whitelisted), but may also indicate an attempt to penetrate product security via the infotainment processor.
