CVE-2023-31029

Unauthenticated code execution via KVM stack overflow

Published Jan 12, 2024 · Updated Oct 25, 2024

Stack-based buffer overflow in the NVIDIA DGX A100 BMC before 00.22.05 allows attackers to execute arbitrary code via a crafted network packet. The host KVM daemon overflows its stack while processing the packet; NVIDIA has not disclosed the responsible protocol field or parsing operation. No authentication is required, but NVIDIA's assessment limits exploitation to local access; exploitation can execute code or crash the BMC.
