With H2HC on hiatus this year, the security community stepped up to create the 307 Temporary Security Conference—and we were proud to be part of it!

We presented our research on vulnerabilities in the CAN BCM protocol in the Linux kernel.

Thank you to everyone who watched!

The slides and exploit demos are now available.

Demo 1: Exploit for UAF read (CAN BCM) to dump shadow file & MySQL root hash.

Demo 2: Exploit for UAF read in CAN BCM (CVE-2023-52922) that leaks encoded freelist pointer and slab object addresses

Memory bugs, such as use-after-free and buffer overflows, are the most exploited vulnerability class; however, AddressSanitizer's 2-4x performance overhead makes it unusable in production.

So, we recommend GWP-ASan, which uses sampling and guard pages to detect memory safety bugs at scale. Learn the technique and how to implement it in your C++ projects using LLVM's scudo allocator:

I want things that are above my reading level, that's how I get better at reading 🤔😁

The Cryptax Award H2 2025 is out! (lol)

Best talks, papers, CTF challenges, tools I encountered in the second half of 2025:

It's a difficult selection, as always, and it is very personal opinion!

Congratulations to those who are listed, and kudos to others :)

There's another researcher, Zhengyu Liu, who's been finding CPython crashes (mostly use-after-free) at breakneck speed (19 in 5 days!): https://github.com/python/cpython/issues?q=is%3Aissue%20author%3Ajackfromeast

Not sure about what technique they're using, but their site states they they favor "leveraging program analysis approaches to detect/exploit/patch vulnerabilities in real-world complex applications and systems".

Their reports are comprehensive, with great presentation and details.

There's a researcher, Jiang Yuancheng, who's doing a great work finding CPython crashes and memory leaks: https://github.com/python/cpython/issues?q=is%3Aissue%20author%3AYuanchengJiang

They've come up with a very clever idea for a new way of fuzzing, made a fine tool out of it, and are reaping great results.

Fuzzing can be a diminishing returns endeavor: you only have so many bugs to find. Their approach has shown itself to cover different areas and kinds of issues well, as shown by their track record.
