CVE-2025-23321Network attack vector

Service crash via invalid-request division by zero

Published Aug 6, 2025 · Updated Aug 6, 2025

Divide-by-zero in NVIDIA Triton Inference Server before 25.07 allows remote attackers to crash the service via an invalid request. NVIDIA has not published the affected code locus or the unchecked value used as the divisor; the bulletin states only that an invalid request triggers the arithmetic fault. Unauthenticated network access to an inference endpoint is sufficient, and successful exploitation interrupts the server without reported data disclosure or modification.
