I don't know what to tell you. I'm sure you have them dead to rights on Linux distro knowledge reliability, but the exploit here is real, and the vulnerability researchers they have on staff are also real. Xint is not generally a slop factory.
It's ironic that the one thing LLMs can't do reliably in this space is "write copy for humans" (I don't trust them for that either).
Honestly I feel like a coding agent review would have caught this issue. I guess if you want to vibe-code your branded CVE web site it's not a bad idea to at least mash /review at the end.
Kind of funny to do something impressive and then ignore the details on the presentation, but perhaps that's not uncommon for security researchers?
