What happened
Schneier’s recent blog roundup links to multiple security stories: a high‑impact Linux kernel local privilege escalation dubbed “copy.fail” (CVE-2026-31431) that abuses the kernel crypto API (AF_ALG) plus splice() to write into another file’s page cache with a working PoC and cross-distro reliability; reports of on‑camera AI age‑verification bypasses (e.g., using a fake mustache); discussion of powerful LLMs (Anthropic Mythos, OpenAI GPT‑5.5) that are effective at finding software vulnerabilities; demonstrations of LLM text‑in‑text steganography; ICE development of smart glasses with facial‑ID
