Because it's a tiresome, tropey, and ultimately invalid complaint. Look downthread at the person who said the FreeBSD commit log was better than this page, despite being inscrutable to security practitioners who don't work in the kernel and not saying a word about proven exploit vectors.
These complaints aren't about what's better or worse for the user community; they're about people trying to put vulnerability researchers in their place.
It's not even a complete description of the vulnerability. It's what the kernel maintainers need to know to understand and fix the bug in the code. The claim that it's superior to the branded vulnerability page gives away the whole game.
As a member of the user community, I only care when it appears on the security list and then that it's patched. And I want to see that on the changelog. And that's about it.
I don't want or need fanfare, marketing or any of that stuff.
It's a bug for fucks sake. There will be people having web pages for Gnome user interface bugs next.
Why not? This weird complaint has been happening since ~2010 and it has never made any sense. You are strictly better off with the website than without it. When it was vulnerability researchers getting all peevish about the status competition they were running, I at least understood where the complaint was coming from, but even among practitioners, branded vulnerabilities are so much the norm at this point that there's no status implication anymore.
No, that commit log is obviously not better than the page explaining the vulnerability and the exploit vectors.
Case in point: what's "tired" about the stack exploitation techniques they're using here?
And, while you're not right, even stipulating that you were, what would that matter? How is anyone better off with less explanation of a vulnerability?
Is that even the fix though? The problem sizeof*groups expression has already been removed by that point. This fixes something but it's not obviously related to the vulnerability description.
Is there something in this website that feels unnecessary? It seems like a good format of sharing high quality information.
This looks like a full bug into a complete root escalation of a kernel. That's hard to do and deserving of praise. The fact that we have a writeup organized like this is awesome.

This is sort of the expert level stuff that I thought HackerNews would most enjoy.
This appears to come from dressing up like Elton John in a feather suit and hiring a marketing team.
