🤯 How can an undefined CPU opcode… have operands?
Welcome to x86 history. 🧠⚙️
0F FF could be decoded + parse operands before 💥 invalid opcode. Then backward compatibility helped keep PADDQ out of its natural slot.
CPU archaeology awaits. 🏺

What’s new in security for Ubuntu 26.10?
Ubuntu 26.10 arrives at a time when AI tools are accelerating vulnerability discovery. To respond to this new threat landscape, the resilience of the underlying OS must limit what an attacker can achieve before a fix is available.
We are reducing the code exposed to attack and replacing memory-unsafe implementations while preserving confinement.

‼️ Node.js Releases Security Updates to Fix High-Severity TLS, DNS, & Brotli Vulnerabilities
Details: cybersecuritynews.com/node-j…
Node.js has released security updates for its 26.x, 24.x, and 22.x branches to address ten vulnerabilities, including four high-severity flaws affecting DNS lookups, TLS certificate checks, and Brotli decompression.
The supplied release details identify 26.12.1, 24.22.1, and 22.23.4 as the patched versions. The most serious potential outcome is remote code execution through the Brotli decoder.
The October security update also covers HTTP connection handling, repeated random values, ZIP processing, and filesystem permission checks.
CVE-2026-111497 affects the Brotli decoder in all three release lines. The supplied advisory describes an out-of-bounds write that permits remote code execution.
