It's a bittersweet result, like finding asbestos in your house. I'd rather know than not, but I would much prefer not having it in the first place.

I understand this work was based on a dated snapshot. Will there be any continuous effort, scanning new PRs as they land, to prevent new weaknesses from being added?

(I am the author the pipeline, just created an account to answer some questions :D) My goal is to work towards a vuln-free Internet. What I observed is that stronger models can find many more vulnerabilities that weaker models cannot. If compute permits (there are other projects to secure besides Linux), I plan to scan Linux again with every newer generation of cyber models.

Have you given thought on how you can use this info to estimate how many vulnerabilities there are?

It will be difficult to claim that the problem has been solved without an idea of how big the problem is.

Given that vulnerabilities are almost entirely unknown, you are inherently trying to measure the undetected.

Is there a way to hypothesize how many vulnerabilities there are and them make a prediction on how many of those will be found by a model to get a sense of how accurate the estimate is?

How can they estimate the existence of a vulnerability that has not been discovered and documented? The hubris to assume zero latent factors!

From what I understand, biologists have the same problem when estimating the number of undiscovered species. One technique is to look at very popular, well studied biomes, and extrapolate the results to less studied biomes. Or ask niche specialists to guess different groups of species and add up the results, which is usually better than trying to estimate the population as a whole.

The errors bars will be huge, but it's better than "zero or more".

I think it is hard to estimate what we don't know. In our first scan when we found 166 vulnerabilities, we wouldn't be able to guess there were 900+ more vulns to find in the code base. We are in the same situation again: now we find 900+ vulns, are there no more vulns to find, 1k more, or even more than that. I think it'd be an interesting benchmark problem if we can have a formally proved safe, large program as the ground truth, inject synthetic vulnerabilities to it, then ask the model to exhaustively find vulns, and use that as a benchmark results.

You’d know better than anyone that nothing can truly be vulnerability free. Even if the attack surface were only the code it would be impossible. But, the attack surface includes you creating the tooling. It includes me the end user. Not just our actions, but our thoughts, conscious and unconscious.

His contract with OpenAI (a line item in the marketing budget) doesnt allow him to discuss these things truthfully. They have tokens to sell.

Careful, there are upsides to that asbestos. It will last and survive much longer than anything else, avoid messing with it and you'll be fine.

Also there are varying types, its worth getting it tested if you need to do a lot of work with/around it.
