久々にCTFで15分遅れてflag取る経験を・・・。

Apple servicからメールが来すぎてるなぁ... 雑spam filteringではさばけないのか。

I’d like to thank all of our teammates and AI :P Thanks to everyone's hard work, we were able to take 1st place.

I played with SuperDiceCodeLovers in this year's DEF CON Quals and solved gitvfs revenge flag 2 challenge

DEF CON patched our QEMU nday, what about a 0day?

We’re releasing write-up for CVE-2026-6068 — a vulnerability in NASM that can be exploited from heap UAF to persistent RCE.

Excellent research from our teammate. Check it out: https://t.co/N30F4YK9SM

💥 Introducing "Dirty Frag"

A universal Linux LPE chaining two vulns in xfrm-ESP and RxRPC. A successor class to Dirty Pipe & Copy Fail.

No race, no panic on failure, fully deterministic. ~9 years latent.
Ubuntu / RHEL / Fedora / openSUSE / CentOS / AlmaLinux, and more.

Even if you've applied the "Copy Fail" mitigation, your Linux is still vulnerable to "Dirty Frag". Apply the Dirty Frag mitigation.

昔から思うけど、Linuxの脆弱性報告方式が雑っていうか。distroには適用されてない脆弱性がkernel commitには普通に上がってることがしょっちゅうあってAIがfull exploit書ける時代だと、危ないと思う。

[Zzoru @zzoru]

実はこれ知っていて、なおkernelCTFに上がってる事もわかっていた。

[Brian Pak @brian_pak]

Hey everyone. We’ve seen the discussions around Copy Fail (CVE-2026-31431) and the disclosure process. We appreciate the passion from distro maintainers, defenders, and the broader Linux community. This is a serious issue, and we want to share some context on our side in good faith. 🧵
