CVE-2023-31024Network attack vector

Unauthenticated code execution via crafted KVM packets

Published Jan 12, 2024 · Updated Jun 3, 2025

Stack-based buffer overflow in NVIDIA DGX A100 BMC before 00.22.05 allows remote attackers to execute arbitrary code via a network packet. The host KVM daemon corrupts stack memory while processing a specially crafted packet; NVIDIA has not disclosed the affected routine or bounds error. No authentication or user interaction is required, and exploitation can also crash the BMC, disclose information, or tamper with data.
