CVE-2022-42278Network attack vector

Authenticated code execution via arbitrary process-memory write

Published Jan 13, 2023 · Updated Apr 7, 2025

Memory corruption in NVIDIA DGX A100 BMC firmware before 00.19.07 allows remote authenticated users to execute code via the SPX REST API. The API permits reads and writes to arbitrary addresses in the IPMI server process instead of restricting operations to valid buffer bounds. High BMC privileges are required; exploitation permits code execution, arbitrary process-memory access, data tampering, or denial of service.
