How can I check if my laptop’s docking station is compromised or contains malware in Linux?

If I suspect that my docking station (USB-C/Thunderbolt) might be infected with malware or used as an attack vector, how can I check for the following in Linux? 1. Could the docking station emulate a keyboard/mouse or inject malicious data? 2. How can I monitor for suspicious activity? 3. What commands help detect anomalies? What kind of security tools or commands are useful for this?
