You can get FuSa (functional safety) certified Linux; to my knowledge this just does not exist for Windows. There may be other situations where the choice does exist, but considering Windows and Linux widely equivalent in this context is not possible.

Neither Windows nor Linux are, to my knowledge, certified for SoL (safety-of-life) applications. And to no surprise considering this is close to (but not quite) a mathematical proof your system can't hang/crash/starve, which is pretty much impossible for anything beyond an RTOS with current tooling.

And they're going to ask how much for the recertification for each CVE fixed? I doubt that'd be cheap.

I didn't have exactly SoL applications in mind, there are plenty of other situations where the stability of a system could cause a risk. Be it just an emergency call center server or a field laptop for looking up license plates - can't leave them unpatched (especially with some of the new legislation) but also downtime from poor updates could be really bad.

FIPS has created an off-kilter perception about "recertification" because they require essentially the entire process when you change a single bit somewhere. Most certifications are not that harebrained.

Also if you need "certified" Linux, you are either already spending resources on it yourself, or paying someone else to do it. This might need adjusting for this new CVE practice, but it's going to be an adjustment and not a reset.

Then pay someone to test and deliver.

That's the thing, resources aren't infinite. Linux offloading that work elsewhere will not have a net positive effect.

The path of least resistance will be taken, which is going to be proportionally less QA, if there was any to begin with.
