Thank you! I'm really happy to hear you did that. But why not mention that in your blog post? I understand not wanting to include a PoC for responsible disclosure reasons, but including it would have added a lot of credibility to your work for assholes like me lol
I honestly hadn’t anticipated someone would think I hadn’t bothered to verify the vulnerability is real ;)
Since you’re interested: the bug is real but it is, I think, hard to exploit in real world scenarios. I haven’t tried. The timing you need to achieve is quite precise and tight. There are better bugs in ksmbd from an exploitation point of view. All of that is a bit of a “luxury problem” from the PoV of assessing progress in LLM capabilities at finding vulnerabilities though. We can worry about ranking bugs based on convenience for RCE once we can reliably find them at all.
I'm too much of a skeptic to not do so lol. Great post though overall, don't let my assholery dissuade you! I was pleasantly surprised that it was actually a researcher behind the news story and there was some real evidence / scientific procedure. I thought you had a lot of good insights into how to use LLMs in the VR space specifically, and I'm glad you did benchmarking. It's interesting to see how they're improving.
Yeah race conditions like that are always tricky to make reliable. And yeah I do realize that the purpose of the writeup was more about the efficacy of using LLMs vs the bug itself, and I did get a lot out of that part, I just hyper-focused on the bug because it's what I tend to care the most about. In the end I agree with your conclusion, I believe LLMs are going to become a key part of the VR workflow as they improve and I'm grateful for folks like yourself documenting a way forward for their integration.
Anyways, solid writeup and really appreciate the follow-up!
