+- How to ~~fix~~ mitigate? In the worst case scenario, 5 "layers" need to be updated: the microcode/firmware, the host OS kernel, the hypervisor, the VM OS kernel, and possibly all the software running on the machine. Sometimes only a subset of those layers need to be updated. In yet other cases, there can be several possible mitigations for the same vulnerability, implying different layers. Yes, it can get horribly complicated.

 A lot as changed since 2018. Nowadays, the industry adapted and this range of vulnerabilities is almost "business as usual", as software vulnerabilities are. However, due to their complexity, it's still not as easy as just checking a version number to ensure a vulnerability is closed.
 
-Granted, we now have a standard way under Linux to check whether our system is affected, vulnerable, mitigated against most of these vulnerabilities. By having a look at the `sysfs` hierarchy, and more precisely the `/sys/devices/system/cpu/vulnerabilities/` folder, one can have a pretty good insight about its system state for each of the listed vulnerabilities. Note that the output can be a little different with some vendors (e.g. Red Hat has some slightly different output than the vanilla kernel for some vulnerabilities), but it's still a gigantic leap forward, given where we were in 2018 when this script was started, and it's very good news. The kernel is the proper place to have this because the kernel knows everything about itself (the mitigations it might have), and the CPU (its model, and microcode features that are exposed).

This tool can't tell you when or if this will be the case. You should ask your vendor about it.
