Admin code execution via IPMI buffer overflow
Published Jan 13, 2023 · Updated Apr 7, 2025
A buffer overflow in the BMC IPMI handler in NVIDIA DGX A100 systems before 00.19.07 allows local users to execute code or interrupt BMC service. NVIDIA has not disclosed which IPMI request, field, or copy operation triggers the overflow in the handler. Exploitation requires high privileges and high-complexity local access, and successful exploitation compromises the controller or interrupts its management functions.

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.
