Green is good in the script output, red is bad. You need to ask questions how to fix it if you get red results and need help. Seems pretty easy to me!
Yes it's easy red is bad, green is good, and not already discovered will be reds next, the problem is; times after times, some new red items are discovered. (and the good news; it's for the moment always before a massive impact)

Quoting from the article:
"Thus far, no attacks actually utilizing Spectre and Meltdown have been spotted in the wild, beyond proof-of-concept work submitted by researchers."
Absence of evidence is not evidence of absence.

I give up, I am going to install fresh and not use that kernel.
I am sitting on Debian Testing, waiting for you guys to get this straightened out. At least it works without holes in the kernel.

Why don't you either patch the kernels and upgrade them. or. drop them and advise the rest of the users to do so.
The risk does not warrant such extreme actions. It could also be rhetorically stated why don't all users change to AMD CPUs?

That's not what I'm saying. Mitigate what you can, subject to your resources and your needs. Don't sell the farm. Don't panic. Reduce your exposure. Practice safe computing. Nobody has been successfully attacked this way, yet.

The kernels are already patched and in the repos. The 5.0-16 Liquorix kernel is also not vulnerable, as the checker output told you.

That does not look like fixing the problem. Why even bring this up, or, use a topic that the average user would not even read? Sorry, I am probably too cautious, but, the main reason I do not use Windows is they have too many mitigating circumstances and it is a hacker's dream. I quit using Manjaro after years testing and stable because the main designer took a vacation and everything went to pot, The white screen of death was the result of changing something in nvidia they had no reason to change when they upgraded two kernels. Sorry if I offended you.

Fixing the problem would Intel recalling and replacing all of its vulnerable CPUs at Intel's expense. Mitigating the problem is patching Linux kernels such that CPU-induced security vulnerabilities can't affect the operating system. It's not Linux's problem, yet they've patched their kernel to prevent Intel's microcode vulnerabilities from being able to be exploited in Linux. That's why it's called a mitigation, not a "fix" or a solution. It's more of a work-around. It effectively fixes the problem, but since the source of the problem is within Intel's microcode that's where an actual "fix" would need to be applied.

What was the problem, exactly?

You should probably open a new thread for this.
