DeepSpeed

DeepSpeed is an AI/machine learning optimization library developed by Microsoft that accelerates training of large language models. This vulnerability has a high severity rating (7.8) and requires local access with user interaction to exploit, but once triggered delivers significant impact across confidentiality, integrity, and authenticity—no authentication is needed. Security teams should monitor for patches expected by June 2026 and implement access controls on systems running DeepSpeed, particularly in development and training environments where user interaction with untrusted code is possible.
