also check the openwall link there, where they discuss it was not backported to LTS kernels until very recently.
Windows has an overwhelming market share in PCs. Exploitable vulnerabilities that let hackers own it are going to be huge news for as long as that remains the case, because it directly impacts the lives and personal data of more people.
That said, I’m seeing lots of people talk about this particular Linux vulnerability, so I’m not even sure what your gripe is.
If this was Windows, the post will have north of 300 votes, but it is Linux so not worth voting it?
It’s being posted all over Lemmy…?

on suse’s part, there are still no fixes: https://www.suse.com/security/cve/CVE-2026-31431.html
No patch on 6.12 LTS and by extension Debian.
Still, my point remains valid.
