This is my team’s work. I’m happy to try to answer questions or take questions back to the team.

And we're hiring! https://openai.com/careers/search/?q=cyber

Do you have a list of the publicly discussed or fixed ones?

(As someone who used to handle nonpublic Linux kernel security reports and is still very interested in this stuff, I’d love to review a small sample of these reports to get a feel for what kinds of issues are being unearthed.)

Also, please don’t stop at LPEs and information disclosures. If you find cases where Linux can be convinced to misbehave or where the implemented semantics don’t make sense, these are good, too. I’ve found plenty of interesting kernel bugs, including some juicy LPEs, and almost none were memory safety errors :)

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?

As models get more advanced and generate an increasing throughput of increasingly higher quality results, how are you determining when to trust its results and when human review is needed on what?

E.g., 948 results is a high number to review in a timely manner unless your team is very large or spending several months combing through the results

EDIT: nvm i shouldve kept reading, answered

> At this scale, manually investigating every report is impractical for our research team. We therefore focused on validating findings that a) were reachable by a low-privileged user, b) required no special capabilities, and c) produced measurable evidence of memory corruption.

Unfortunately no remote openings and a very limited set of offices. You’re missing out on a lot of talent.

I'd like to see a break down by age of code and part of kernel (drivers, networking, core ,etc ..)

ahsillyme • today at 12:31 AM

Thanks. I'm not a programmer so I can't understand what is happening in the kernel by looking at the changelog, so I'll ask: Are the problems remediated structurally so that nothing like it can occur in the future, rather than just patching it up? Are there "lessons learned" that are being applied and documented here (like, "this problem looks like it's shape transports to other subsystems as well, let's fix them all in a disciplined way")?

The high number is really impression to the point of making me skeptic. Are these distinct vulnerabilities or are a lot of the related in the way vulns often are?

The article says "The target virtual machines ran a stock desktop operating system". Are the vulns in the kernel specifically or does this include software running as root?

Thanks for trying to help on the defensive side!

And, well, since you didn't _specifically_ ask for questions about the blog post:

Why are you not quitting your job in protest and screaming at the top of your lungs about it, seeing so closely what these models are capable of that your company is creating? There exists now something that is able to find 948 kernel LPE vulnerabilities. How, exactly, will humans be able to control and contain, say, next year's models for a nonzero amount of time?

My 2 cents: it would be beneficial to involve companies like RH and the teams behind many distros to work through those, it's not just about validating and patching but also about delivering them to the systems involved, a lot of people need to be involved, hence collaboration is required

0x00cl • today at 1:58 AM

I'm going to assume that there was "old" code that caused LPE vulnerabilities, but, The Linux Foundation have their own project Sashiko (https://sashiko.dev/), which analyzes each commit to the Linux Kernel for bugs and vulnerabilities using Googles models, my question is then, how many of the vulnerabilities you found were also caught by Sashiko?

Would be nice if the page could be readable without.

I wish these blog posts included statistics on the categories of deficiencies that cause these vulnerabilities, and proposed measures to avoid them

A system that admits THOUSANDS of such vulnerabilities is certainly flawed in several fundamental aspects

...and then proceeds to never answer a single question. Classic.
