For those just learning about LibGen because of the reporting on Meta and other companies training LLMs on pirated books, I’d highly recommend the book Shadow Libraries (open access: https://direct.mit.edu/books/oa-edited-volume/3600/Shadow-LibrariesAccess-to-Knowledge-in-Global).
I just read it while working on the Wikipedia article about shadow libraries, and it’s a fascinating history. https://en.wikipedia.org/wiki/Shadow_library
I fear the already fraught conversations about shadow libraries will take a turn for the worse now that it’s overlapping with the incredibly fraught conversations about AI training.
The Trump family has reportedly had conversations about acquiring a stake in Binance — as Binance founder and former CEO Changpeng Zhao is reportedly seeking a pardon from the president.
Let's also talk about our failures!
We tried to make a consortium for a cool EU-funded project about malware analysis, but didn't manage to do it in time. 🫤
We'll try again! If you're an SME owned and controlled in the EU, feel free to get in touch 💪
@linkersec The bug exploited in the article appears to have also been reported by syzbot last year. And looks like it haven't been fixed upsteam yet, only in Ubuntu.

Linux kernel hfsplus slab-out-of-bounds Write
Outstanding article by Attila Szasz about exploiting a slab out-of-bounds bug in the HFS+ filesystem driver.
The author discovered that Ubuntu allows local (not remote/SSH'd) non-privileged users to mount arbitrary filesystems via udisks2 due to the used polkit rules. This includes filesystems whose mounting normally requires CAP_SYS_ADMIN in the init user namespace.
The article thoroughly describes a variety of techniques used in the exploit, including a cross-cache attack, page_alloc-level memory shaping, arbitrary write via red-black trees, and modprobe_path privilege escalation.
