RIP ๐Ÿชฆ Craziest bug I have ever seen in my 10 years of being in the iOS scene. I really wish Apple would stop being so anti consumer. Everyone who knew about this had an SRD suddenly overnight and nothing bad happened.

As others noted, Apple patched the not-so-secret server side bug. It enabled root access and jailbreaking even on iOS 27.2b3 (18 Pro Max). A public release would've meant an instant patch, so it stayed private. Despite efforts to preserve it, it's cooked. RIP ๐Ÿชฆ๐Ÿ˜ญ

Introducing the Frag Gap (CVE-2026-53362/CVE-2026-53366)! A bug in ipv4/ipv6 that I found together with @physicube, and it (used to) let you freely get root. This could affect Android too, but we don't have a device so... Full details are written up in both EN and KO at blog.qwerty.or.kr/en/posts/cโ€ฆ If you're curious about the code, just checking out github.com/qwerty-po/securitโ€ฆ is enough. We've got a few more fun bugs, and we'll post them as we find the time. This is just the Hitchhiker's Guide to the Linux Kernel. Don't Kernel Panic!

๐Ÿšจ Anthropic just showed a 27-minute workshop on how to actually do prompts for Claude. Taught by the people who built it. Free. No registration. No paywall. I've seen $300 courses that don't cover what they teach in the first 8 minutes. Watch it and bookmark it now.

Someone fed our Linux kernel exploitation blog post into Claude, and it casually coughed up another vulnerability. On one hand, this is the beauty of open research and sharing. On the other hand, Claude scares me. Send help! linkedin.com/posts/yochai-eiโ€ฆ git.kernel.org/pub/scm/linuxโ€ฆ
