Kernel code execution via KVM memory corruption
Published Sep 20, 2023 · Updated Sep 24, 2024
NVIDIA DGX H100 BMC host KVM daemon allows authenticated local attackers to corrupt kernel memory and potentially execute kernel code. The daemon mishandles attacker-controlled KVM input, permitting corruption of kernel memory. Exploitation requires authenticated local access to the BMC service and can result in code execution, denial of service, privilege escalation, information disclosure, or data tampering.

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.
- Affected versionversion=0 <23.08.07
- Affected versionversion=All versions prior to 23.08.07
