Preface: NVIDIA collaborates with Supermicro for their server solutions, including the use of Supermicro’s BMC (Baseboard Management Controller) in certain systems. Supermicro provides a range of server solutions optimized for NVIDIA’s platforms.

Background: The NVIDIA Hopper HGX for 8 GPUs has several standout features:

High Performance: It hosts eight H100 Tensor Core GPUs, which are designed for AI and high-performance computing (HPC) workloads.

Advanced Connectivity: Each H100 GPU connects to four third-generation NVSwitches, enabling a fully connected topology. This setup allows any H100 GPU to communicate with any other H100 GPU concurrently at a bidirectional speed of 900 GB/s.

Enhanced Bandwidth: The NVLink ports provide more than 14 times the bandwidth of the current PCIe Gen4 x16 bus.

Vulnerability details: VIDIA Hopper HGX for 8-GPU contains a vulnerability in the HGX Management Controller (HMC) that may allow a malicious actor with administrative access on the BMC to access the HMC as an administrator. A successful exploit of this vulnerability may lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering.
