Report them separately and clearly. Don't hide by omission the fact that they are security bugs (common practice in Linux apparently). Coordinate with major vendors how to push fixes.

That's exactly how it works. Vulnerability found, reported and fixed in secret and when everything is in place everyone is informed to update.

They are generally more important than other bugs so you should put more effort into detecting and preventing them. E.g. using fuzzing, sandboxing, formal methods, safer languages, safety annotations, etc.

I don't want to sound condescending, but what do you think all this talk about Rust and AI tools is about?

In the end you want to prevent all bugs from happening. Some filesystem bug randomly deleting data can be just as catastrophic as remote code execution.

And if some feature turns out to be a gaping security hole you'll quickly see it turn into a bug. That's what the quote is about. Every security issue is a bug so it has to be handled like a bug and squashed.

Priority in bugs exist independent of them being security related or something else. A critical bug will always get the highest priority fix.
