An AI Found a Critical Linux Bug, Then Wrote the Exploit in 53 Minutes

CVE-2026–98432 is a use after free flaw in the Linux kernel’s TCP code, rated 9.8 out of 10, that can hand a remote attacker root on a server running multipath TCP. What makes it different from the usual critical CVE is who found it. An unreleased internal AI model at Anthropic spotted the bug, then built a working root exploit in about 53 minutes. I went through what the flaw is, who is patched, and why the AI part changes the math for defenders.

Linux Deleted a $10 Billion Intel Chip in One Commit. Itanium Took 23 Years to Die

Intel and HP spent roughly $10 billion building Itanium, the chip that was supposed to replace x86 forever. Analysts projected $38 billion in sales by 2001. In Linux 6.7, released in January 2024, the kernel deleted about 65,000 lines of Itanium support in one go, because nobody was left to maintain it. I went through why the most expensive bet in CPU history ended as a pile of deletions, and what it taught Linus Torvalds about anyone who promises the future needs a clean break.

AI Is Quietly Dismantling the Thing That Kept People on Windows and macOS

For 30 years the reason you could not simply switch to Linux was the software. Photoshop, Office, the apps you needed and the file formats they locked you into. In October 2026 a single developer used Claude Code to rebuild Adobe’s core creative apps in Rust and gave them away. I think the moat that protected proprietary software just sprang a leak, and the legal fight over whether that is allowed is going to be the real story.

How Intel, Microsoft, and Linux Took Down the UNIX Server Kingdoms

Going into the 1990s, a serious enterprise server meant a proprietary UNIX system running on custom RISC silicon, and it cost a fortune. By 2005 most of that market had been eaten by cheap Intel boxes running either Windows or Linux. I went back through how that happened, because it is one of the cleanest examples in computing history of a business model getting beaten on economics while its technology stayed ahead.
