CVE-2025-23331Network attack vector

Unauthenticated service crash via oversized memory allocation

Published Aug 6, 2025 · Updated Aug 6, 2025

Denial of service in NVIDIA Triton Inference Server before 25.06 allows remote attackers to crash the server with an invalid request. NVIDIA has not identified the request handler or field; it states that an invalid value drives an excessively large allocation and segmentation fault. No authentication or user interaction is required, and exploitation interrupts inference service without reported data exposure or modification.
