CVE-2023-0205Network attack vector

Service interruption via insufficient access-control granularity

Published Apr 22, 2023 · Updated Feb 4, 2025

Access-control weakness in NVIDIA ConnectX Firmware before 35.1012 allows remote authenticated users to interrupt adapter service. NVIDIA has not disclosed the firmware interface, access-control boundary, or operation that mishandles the unprivileged request. Network access with low privileges is required, and the reported consequence is limited to reduced availability.
