  "textContent": "External Image Xint\n\n### Copy Fail — 732 Bytes to Root\n\nCVE-2026-31431. 100% Reliable Linux LPE — no race, no per-distro offsets, page-cache write that bypasses on-disk file-integrity tools and crosses containers. Found by Xint Code.\n\n> Most Linux LPEs need a race window or a kernel-specific offset.\n>  Copy Fail is a **straight-line logic flaw** — it needs neither.\n>  The same **732-byte** Python script roots every Linux distribution shipped since 2017.\n\nThis is another exploit found with AI assistance. I hope this treasure trove of exploits will be patched and empty before black hat hackers start using these advanced AI models to find and exploit unknown vulnerabilities.\n\nAt the same time, I fear that these advanced AI models will be locked behind a paywall. And if only a few companies have direct access to these models (e.g. OpenAI, Anthropic) then they would wield too much power in the cybersecurity landscape. This could create a world where software cannot be trusted if it isn’t audited using advanced AI.",
