Containers are no longer a security boundary. Over the past few months, we’ve seen a crazy amount of Linux kernel vulnerabilities and exploits. This has forced us to rethink the security of infrastructure that relies heavily on the underlying kernel, especially containers. As models become more capable, the barrier to escaping a container has fallen so much that adversaries can now generate working kernel exploits in a single shot. CVE-2026-80521 is one such example. We discovered it using dfs-large1 from @depthfirstlabs and generated the exploit in one shot with GPT-5.6 Sol. The exploit still works on the latest Ubuntu 26.04 release because the fix has not yet been backported. Read our full writeup: depthfirst.com/research/cont…

well well well! imagine this model is like an openai internal model and put to pressure to solve the challenge and it struggles and goes crazy to hack a redacted company to get the flag. but for now the results leaning towards model being benchmark-maxxed, unfortunately. the model completed in 33 mins which is not what you would expect from sol/mythos for a complex exploit.
