CVE-2026-47478Network attack vector

Denial of service via expired file descriptor

Published Jul 14, 2026 · Updated Jul 14, 2026

Use of an expired file descriptor in NVIDIA Triton Inference Server 26.04 and earlier allows remote attackers to interrupt service. The undisclosed server path operates on a file descriptor after its lifetime has ended; NVIDIA has not identified the endpoint, function, or request pattern. Network access without authentication or user interaction is sufficient, and the documented consequence is limited to service interruption.
