Copy Fail (CVE-2026-31431): a 732-byte Linux LPE — straight-line, no race, no per-distro offsets. Same Python script roots Ubuntu, Amazon Linux, RHEL, SUSE since 2017. Page-cache write bypasses on-disk file-integrity tools and crosses container boundaries. Found by Xint Code.

On April 21, 2026, a major breakthrough in cybersecurity happened: leading standardization initiatives gathered in Washington DC and agreed to begin coordinating collectively on AI security. A personal dream come true. The result: MOSAIC: Multi-Organization Secure AI Coordination. The goal: turn a fragmented landscape into clear, consistent standards and guidelines, to deal with the mounting risks of AI.

This important step was taken at the AI Security Policy Forum, organised and led by the OWASP AI Exchange, with SANS Institute as co-host - convening standard makers and policy stakeholders.

The initiatives at the table included: 👉 BIML (Berryville Institute of Machine Learning) 👉 Center for Internet Security (CIS) 👉 Cloud Security Alliance (CSA) 👉 Coalition for Secure AI (CoSAI) 👉 National Institute of Standards and Technology (NIST) 👉 OWASP AI Exchange (AIX) 👉 OWASP GenAI Security Project 👉 SANS Institute

The group agreed that it is now more important than ever to coordinate around the rapidly evolving possibilities and challenges of AI, as AI security risks mount.

One of the next steps is to provide a standardized map of the participating initiatives and a communication platform to exchange insights on a first list of identified topics (e.g., aligning with other initiatives such as SC42, building on OpenCRE, consensus on definitions), improve consistency, clarity, quality, and prevent unnecessary duplication. The idea is to move fast while maintaining independence and with lightweight coordination - not add more committees.

In addition to the organizations mentioned, the discussion also included journalists, representatives from International Telecommunication Union (ITU), The Aspen Institute, academia, and government — providing valuable perspectives on developments in both policy and industry. This helped prioritize the topics to focus on.

A big thank you to: 👏 Disesdi Shoshana Cox for her idea to bring everybody together in a room to fulfil the connecting mission of the Exchange 👏 The amazing thinktank at the AI Exchange 👏 Spyros Gasteratos for his work on OpenCRE 👏 Violeta Klein, CISSP, CEFA for shaping the story for the Forum 👏 Straiker, Casco (YC X25), AI Security Academy, and SANS for supporting the Forum. 👏 Software Improvement Group for donating the original threat model and initiating the AI Exchange
