📢 An RbTree Family Drama: Exploiting a Linux Kernel 0-day Through Red-Black Tree Transformations by William Liu & Savino Dicanosa
Say hello to Eternal Tux🐧, a 0-click RCE exploit against the Linux kernel from KSMBD N-Days (CVE-2023-52440 & CVE-2023-4130) willsroot.io/2025/09/ksmbd-… Cheers to @u1f383 for finding these CVEs + the OffensiveCon talk from gteissier & @laomaiweng for inspiration!
Hey, for anyone who wanted to see this slide deck, it was a keynote about the 0day market, but it commented on public research vs saleable products. I have put it here: github.com/mdowd79/presen… // cc @chompie1337 @bsdaemon

Our CVE-2024-50264 with @_qwerty_po has won the Best Privilege Escalation category at the 2025 Pwnie Awards. Thank you, @PwnieAwards!!
Here is our 0day for kernelCTF🩸 - 82k bounty - quickest submission ever - all instances pwned😎 syst3mfailure.io/rbtree-family-… Disclaimer: We apologize for abusing the red black tree family. Turning grandparents against grandchildren is only acceptable in the context of pwn😤

Exploit write-ups for our 🚨latest 0-day🚨and the tragedy that swept the red black tree family dropping soon 👀 Here is a tiktok style video for those of you with no attention span thanks to slop and social media. Turn on the audio!!!

Oops, we just pwned the kernelCTF mitigation instance with a 0day😳 Our fellow pwner syst3mfailure has picked up pigeon feeding as a hobby to help him cope with the insanity
🚨🚨🚨We just broke everyone’s favorite CTF PoW🚨🚨🚨 Our teammate managed to achieve a 20x SPEEDUP on kctf pow through AVX512 on Zen 5. Full details here: anemato.de/blog/kctf-vdf The Sloth VDF is dead😵 This is why kernelCTF no longer has PoW!

Knowledge sharing and relaxing with the team!
We are back😎 Say hello to our kernelCTF submission for CVE-2025-37752🩸 Who would have thought you could pwn a kernel with just a 0x0000 written 262636 bytes out of bounds? Read the full writeup at: syst3mfailure.io/two-bytes-of-m… 👀
No mention of Qualys, Vigilant? Smh
I've just published a new blog post detailing how I developed a deterministic kernel exploit for iOS. Enjoy! alfiecg.uk/2025/03/01/Tri…
Blog post I wrote about an unexpectedly vulnerability we discovered in the TCP subsystem of the Linux kernel. This one is interesting because it can lead to a UAF even with the reference counter saturation mechanism present. I hope you enjoy it.

Timelines like this (from: osec.io/blog/2024-11-2…) are why companies use #grsecurity, where the ROP, DirtyPipe, msg_msg, modprobe_path, etc techniques are all long dead:
Full kernel read/write with CVE-2023-32434 using a deterministic exploit strategy (100% success rate)! arm64e is certainly not as easy, but for now all of arm64 should be doable with this strategy. Shoutout to @staturnzdev and @imnotclarity for lots of help and ideas.
code auditing for exploitable bugs is a lot of labor. building fuzzers to find exploitable bugs is a lot of labor. stop trying to find shortcuts. expect to put in a lot of time and sustained effort. can’t be frustrated when you haven’t put in the effort
