CVE-2025-33201Network attack vector

Unauthenticated denial of service via oversized payloads

Published Dec 3, 2025 · Updated Dec 3, 2025

Denial of service in NVIDIA Triton Inference Server before r25.10 allows remote attackers to interrupt inference via oversized payloads. NVIDIA identifies an improper exceptional-condition check but has not disclosed the request handler or operation that fails on oversized input. Network access is sufficient without authentication or user interaction, and the documented consequence is limited to service interruption.
