CVE-2026-110912: Arpbleed
CVE-2026-110912 is my first published CVE! The fix is merged upstream and the record is live in the database. It lives in a 23-year-old corner of DragonFly BSD. The ARP input path trusts two one-byte length fields from any packet on the wire. Ask for a 200-byte hardware address and the kernel builds its reply with a 200-byte memcpy out of a 6-byte buffer, and sends the excess back to you. Same trick on the protocol length reads straight off the kernel stack. One crafted ARP request on the same L2 segment leaks up to 249 bytes of heap and 251 bytes of stack, kernel pointers included. No authentication, and nothing in the victim’s logs.
GLM-4.7-Flash Abliteration Benchmarked: Heretic vs HauhauCS vs Huihui vs Abliterix
GLM-4.7-Flash is a 59 billion parameter reasoning model from Zhipu AI that uses 64 specialist expert modules per layer. I benchmarked four pre-existing abliterated variants against it and discovered something unexpected in the maths benchmarks. The raw scores look terrible for some variants, but the models can actually still do the maths. They just overthink and run out of tokens before writing their answer. And the weight forensics on one of those variants led to a bigger story about plagiarism.
