Here's a general question, are these vulnerabilities hitting Linux more than BSDs due to hit being a larger target or because its architecture is less secure by design?
AFAIU, Linux and the BSDs have basically the same architecture - the BSDs just value secure and simple, understandable code more highly than Linux vs features and performance.
It’s two things. 1. Less eyes are on the bsds
2. Bsds don’t have the same optimizations that Linux has. Bsds generally try to pursue corrrectness
That being said there were just a bunch of vulnerabilities in freebsd
macOS has had its own dirty cow attack and I know there’s for sure more memory ones just based on the way the xnu kernel works.
So no Linux isn’t really worse per say
