Code execution via unchecked IPMI buffer copy
Published Jan 13, 2023 · Updated Apr 7, 2025
Buffer overflow in the NVIDIA DGX A100 BMC IPMI handler before 00.19.07 allows local users to execute code or crash the controller. The IPMI handler copies input without checking its size, overflowing a destination buffer; NVIDIA has not identified the affected request. Low-privileged local access is required; successful exploitation can crash the controller or execute code in its security context.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
