CVE-2025-33238Network attack vectorHinoki check available

Service crash via unprotected model-list access

Published Mar 24, 2026 · Updated Mar 24, 2026

Race condition in NVIDIA Triton Inference Server before 26.01 allows remote attackers to crash the service through SageMaker HTTP requests. The SageMaker service accesses its model list without synchronization, so concurrent request handling can raise an exception and terminate the server. SageMaker handling is disabled by default, so exposure requires that optional HTTP service to be enabled.
