MAC OS – several Linux security vulnerabilities exposed as part of a recent network scan. How to fix?

One of my company computers – a Macbook Air, was shown to have security vulnerability as part of a recent external network scan.

The issues are related to Linux 4.0. The MAC OS is a UNIX flavor, not Linux (FYI – I’m not an expert at all!!). I’m wondering if these vulnerabilities are perhaps related to the router connecting the computer to the internet? Maybe the router is running on Linux?

These are the issues:


Is there a way to patch/fix these issues? I upgraded to Big Sur, yet the vulnerabilities remain.

Does anyone have any ideas?
