> Another win for the Linux security model

I swear, OSs have become sports teams.

Linux's 'security model’ has plenty of holes. The very fact the kernel and much of its user-mode is written in C almost guarantees that its security model is worthless. The Linux ecosystem operates on trust and respect that can and has been easily abused by bad actors to provide supply-chain pwnage.

There have been so many zero-click local privilege escalation CVEs I've lost track.

AUR is an effectively unmoderated user repo. It’s not Arch Linux’s core repository, nor is it enabled by default or indeed even possible to use without manual downloads from outside the package manager.
There's still a security there though.

You have confidence you are actually downloading the same foo as everyone else. And if there were an issue there would be pushback. Not so if you get some random exe from warez.com

Yes it isn't perfect, it's still a lot better than windows land.

I think you can probably find a better example, even if less recent. The AUR is unofficial and not properly vetted in the same way as the actual Arch repos, Debian repos, etc.

Implementation bugs are not holes in the security model. Linux has plenty of those, as does Windows.

Windows security model trusts, downloads, and immediately executes arbitrary software when a new untrusted device is plugged in, without asking the user.
