The second comment on the page sums up what I was going to point out:
I’d be careful making assumptions like this ; the same was true of exploits like Spectre until people managed to get it efficiently running in Javascript in a browser (which did not take very long after the spectre paper was released). Don’t assume that because the initial PoC is time consuming and requires a bunch of access that it won’t be refined into something much less demanding in short order.
Let’s not panic, but let’s not get complacent, either.
That’s the sentiment I was going for.
There’s reason to care about this but it’s not presently a big deal.
I mean, unpatchable vulnerability. Complacent, uncomplacent, I’m not real sure they look different.
Can’t fix the vulnerability, but can mitigate by preventing other code from exploiting the vulnerability in a useful way.
