serial

No clear evidence of intentional malware (no exfiltration to external systems, no credential theft, no obfuscated payloads, no eval/exec, no hardcoded secrets, no reverse shell). However, the code is security-sensitive: it creates a localhost TCP server that allows any local client to inject arbitrary bytes into a serial device, and it spawns socat to create a virtual serial PTY link at a user-provided path. If used in an untrusted local environment, it could be abused for unauthorized serial control or for denial-of-service. Additional risk may exist if vserial_link/workspace inputs are not validated by the unseen helper functions.
