Containers are a useful primitive, but very limited in terms of an actual security boundary Back in 2007 when me and my team presented at BlackHat and DefCon about our kernel exploitation research and demonstrated various 0-days and N-days for different operating systems it was cutting edge In 2026, when AI agents are able to automate a large part of the process, kernel exploitation is becoming pretty mainstream Physical separation (dedicated systems for each workload) is always best, but at the very least use virtualization and avoid exposing the attack surface from your host kernel to anything you want to isolate
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

@MagneticNorse You can say that the analysis suggests 1/29 fixed but there wasn’t enough in my opinion to justify that result, hence why my report says what it says
I 100% feel that and experience it fairly often. Given I don’t do bug bounty or ask for any type of recognition or anything. I just ask that the issues are fixed and ima post em 90 days from when I contact them the first day regardless at least without justification + some other stuff. If could also be worse. Could have them retaliate against you behind your back/slander you and loose your day job. Not that I would know what that’s like.😒 Ever want to chat lmk
I’m not making any claim outside of my report. Originally my analysis indicated that 1/29 has been fixed. Just there wasn’t enough evidence to make that claim officially imo. However for example the analysis indicates that the 7 unconfirmed are not remediated, just can’t be sure without the physical device (just based off the firmware image).
@HIBFlocked @bennjordan They don’t sound like them, they are them… I released my analysis and remediation test report a few days ago. Peep it. github.com/GainSec/anti-c…

you can just hallucinate the entire internet with Qwen 3.8 27b running at 2,000 tokens/second? part 2 of turning @cerebras + @Alibaba_Qwen 3.8 27B into an OS: built an offline browser with zero network calls and mounted it directly the JIT ubuntu desktop. no wifi. no scraping. zero packets sent to external CDNs. you search a site, set a year, and qwen 27b at 1,950 tok/s synthesizes the entire DOM on the fly. here is youtube in 2045 vs 1999: → search google for youtube inside the OS → scrub to 2045: instant futuristic feed → scrub to 1999: raw web 1.0 time capsule in seconds at this speed, browsing isn't retrieving files from a server, it's querying an alternate reality. a 2D browser window is just step zero. imagine full operating systems, virtual worlds, and complex simulation engines existing purely as model weights. zero gigabytes stored on disk, just pure interactive reality streamed on demand. What else becomes a possibility with the qwen 3.8 27b (dense) at 2000 tokens/sec?
Operating System powered by Qwen 3.8 27B at 1950 tokens/sec! here is what 1,950 tokens/second @Alibaba_Qwen's 3.8 27b actually looks like on @cerebras: i wrote a minimal python web server that turns cerebras inference into a live operating system. zero apps on disk. when you
