@_qwerty_po and I exploited a VSock 1-day in Google kernelCTF back in *February*, securing $71,337 🥳 (CVE-2025-21756, exp237/exp249) And I’ve just published the write-up: github.com/google/securit… A kernel developer reviewing a patch for a separate VSock bug I submitted…
🚨🚨🚨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!
I wrote-up how I used o3 to find CVE-2025-37899, a remote zeroday vulnerability in the Linux kernel’s SMB implementation. Link to the blog post below 👇
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… 👀
I’ve posted a detailed explanation of why the claimed ESP32 Bluetooth chip “backdoor” is not a backdoor. It’s just a poor security practice which is found in other Bluetooth chips by vendors like Broadcom, Cypress, and Texas Instruments too. darkmentor.com/blog/esp32_non…

I believe this sample is proof that J-magic is strongly related to SEASPY2 as Lumen suspected: virustotal.com/gui/file/9bb7a… Seems to be the only SEASPY2 sample on VT, but it contains the same public key as J-Magic so same operators. blog.lumen.com/the-j-magic-sh…

The libarchive e8 vulnerability is actually really cool, but the ZDI advisory doesn't explain why it's so wild lol. For some reason, I know about RAR filters, so let me provide the background. 🧵 1/n
