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?

Re:Local privilege escalation vulnerabilities in Linux by asdff on Thursday November 05, 2026 @01:33AM (#50375900)
How can they estimate the existence of a vulnerability that has not been discovered and documented? The hubris to assume zero latent factors!
Re:Local privilege escalation vulnerabilities in Linux by BoppreH on Thursday November 05, 2026 @08:07AM (#50378647)
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".

Re:Local privilege escalation vulnerabilities in Linux by ky1ebot1337 on Thursday November 05, 2026 @02:44AM (#50376320)
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.
Re:Local privilege escalation vulnerabilities in Linux by asdff on Thursday November 05, 2026 @01:32AM (#50375896)
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.
Re:Local privilege escalation vulnerabilities in Linux by lifeisloving on Thursday November 05, 2026 @03:04AM (#50376445)
llms cannot just find deep vulnerabilities by themselves, they are basically super fuzzers who need to be steered by someone with deep experience. You're selling lies.

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.

Re:Local privilege escalation vulnerabilities in Linux by farisght on Wednesday November 04, 2026 @07:01PM (#50373145)
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

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.

Re:Local privilege escalation vulnerabilities in Linux by lifeisloving on Thursday November 05, 2026 @03:14AM (#50376525)
Why would they review the results? They want to publish flashy metrics, this is a marketing team not an actual cyber dept. Cant risk discovering that 35% of your results are due to reward hacking and ruining the headlines you were hired to create.
Re:Local privilege escalation vulnerabilities in Linux by ahsillyme on Wednesday November 04, 2026 @07:31PM (#50373404)
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")?

These are distinct vulnerabilities counted by the number of patches. The patch generation system performs variant analysis. So, each patch can potentially stop multiple exploits. The raw exploits number is higher than what we reported in the post. We don't want to cause the confusion why #patch != #exploit, so we used the smaller number there. These vulns are all kernel specific. Userspace software running as root was not in scope of the analysis.
Re:Local privilege escalation vulnerabilities in Linux by IshKebab on Thursday November 05, 2026 @02:56AM (#50376396)
I'm not skeptical. Linux has had so many LPE bugs in the past that most people consider it to be a "best effort" thing and nobody actually relies on it. Shared machines are mostly used in companies or universities as a kind of admin tool - the users are more or less trusted.

The only exception I know of is Android. It would be interesting to know how many of these vulnerabilities work there. Can't be zero anyway...

Re:Local privilege escalation vulnerabilities in Linux by emmelaich on Wednesday November 04, 2026 @07:51PM (#50373585)
I'd like to see a break down by age of code and part of kernel (drivers, networking, core ,etc ..)
Re:Local privilege escalation vulnerabilities in Linux by 0x00cl on Wednesday November 04, 2026 @08:58PM (#50374127)
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?
Re:Local privilege escalation vulnerabilities in Linux by paxy on Wednesday November 04, 2026 @10:08PM (#50374660)
If Sashiko had found them then they wouldn't have been merged, so my guess is 0
Re:Local privilege escalation vulnerabilities in Linux by 0x00cl on Thursday November 05, 2026 @03:28AM (#50376638)
That's fair, but I guess the question is whether analyzing each commit can find vulnerabilities or it takes more than that (aside from using Google models). It is possible they might have dismissed Sashiko review because they thought it wasn't possible or didn't make sense.

Then the question becomes how many vulnerabilities Sashiko didn't catch (If they use/review Sashikos review)

Re:Local privilege escalation vulnerabilities in Linux by amluto on Wednesday November 04, 2026 @11:54PM (#50375361)
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 :)

Re:Local privilege escalation vulnerabilities in Linux by mofeien on Thursday November 05, 2026 @12:05AM (#50375426)
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?

Re:Local privilege escalation vulnerabilities in Linux by asdff on Thursday November 05, 2026 @01:27AM (#50375870)

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

I think you'd be surprised that top tier talent (and people in general) usually don't worship money and aren't willing to degrade their standard of living for an extra 75k annually after taxes.
Re:Local privilege escalation vulnerabilities in Linux by comment0r on Thursday November 05, 2026 @03:28AM (#50376636)
I suggest you update yourself on the monetary incentives/benefits for employees that US frontier labs provide. 75k is a drop in the bucket of the amount of money those employees gain in an IPO event, let alone bonuses.
Re:Local privilege escalation vulnerabilities in Linux by xandrius on Thursday November 05, 2026 @04:47AM (#50377226)
You should also upgrade yourself on what people expect nowadays. Might not be top talent but before I return to an office, hell will freeze over.
Re:Local privilege escalation vulnerabilities in Linux by saagarjha on Thursday November 05, 2026 @08:47AM (#50379010)

Re:Local privilege escalation vulnerabilities in Linux by lifeisloving on Thursday November 05, 2026 @09:06AM (#50379225)
You guys have been watching too many AI silicon valley hype youtube content.

OpenAI has 5k employees now.

Yes, you see these headlines about ml researchers getting paid a ton, well thats because there's 5k of them on Earth.

Unless you're a VP or PhD you're not getting life changing compensation. And guess what, all those people can get similar compensation elsewhere without slaving away 4 days a week in an office in San Francisco.

Your average employee is not making an extra 750k. You know you can look at compensation online you cant just do vibes based analysis and just invent your own reality. Find me a position at OpenAI thats paying 750k compensation.

A lot of us already make a lot of money. It’s not about the money. It’s about the work. I would love to work on the things OpenAI is working on. I don’t expect it would be much of a pay raise. But I’m not moving my family for it.

Re:Local privilege escalation vulnerabilities in Linux by dada216 on Thursday November 05, 2026 @05:34AM (#50377536)
My 2 cents: it would be beneficial to involve back the 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
Re:Local privilege escalation vulnerabilities in Linux by saagarjha on Thursday November 05, 2026 @08:52AM (#50379069)
I’ve always felt that the problem after finding all of these is that you’re going to have to patch and upstream them. I assume you’ve probably asked your models to do that but at this rate you’re probably bottlenecked on people to review these and then the kernel maintainers are likely also heavily time constrained on their side to do the same. What ideas do you have to improve this situation? Do you foresee a process where you’re not just finding an ever increasing number of bugs and instead can bring that number down with different approaches to attacking the problems (e.g. designing new mitigations?) I don’t really see this described in your career listings so it’s hard to tell what you’re doing in preparation of better models :)
