CVE-2025-23329Network attack vectorHinoki check available

Unauthenticated service interruption via shared-memory corruption

Published Sep 17, 2025 · Updated Sep 17, 2025

Improper access control in NVIDIA Triton Inference Server before 25.08 allows remote attackers to corrupt Python-backend shared memory. The Python backend permits clients to identify and access its shared-memory region without adequate access control. Network access to the shared-memory APIs is sufficient; corruption can interrupt the service, with no reported data disclosure or modification.
