    does this mean Linux has a virus and our computers are compromised and
    our data is at risk? (my knowledge of Linux/LM is very basic)

    If you have updated your system the problem is already fixed for most distros. Even if you have not in most cases for home users the exploit requires physical presence.

    I do all the updates the update manager shows. I'm using Linux Mint 22.3
    (home user only), so it seems I am ok then.

    The vulnerability just means that anybody who has nonprivileged user
    access to execute arbitrary (nonprivileged) commands on your machine
    can promote themselves to privileged access.

    Do you have multiple users on your machine? Typically, the answer
    would be ?no? -- I imagine it?s just you.

    Even public-facing servers would normally run very restricted apps
    when offering services to all and sundry.

    yes, just myself

    Seems to me the takeaway from the last article is to run this command:

    grep -qE '^algif_aead ' /proc/modules && echo "Affected module is loaded" || echo
    "Affected module is NOT loaded"

    A one liner. In my 22.3 it shows NOT loaded.
