What happened
Collection of Bruce Schneier blog items (May 2026) highlighting multiple high‑impact security issues: (1) copy.fail (CVE-2026-31431) — a widespread Linux kernel local privilege escalation that abuses the crypto API and splice() to corrupt page cache and achieves root across major distributions with a public PoC; (2) YellowKey — a published zero‑day that reliably bypasses default Windows 11 BitLocker protections but requires physical access to the machine and a TPM; (3) AI security concerns — Anthropic’s Claude Mythos Preview and OpenAI’s GPT-5.5 demonstrate strong capability at finding code/vm
