NVIDIA Hopper HGX 8-GPU: Internal Asset Exposed to Unsafe Debug Access Level or State
CVE-2024-0114 is a high-severity internal asset exposed to unsafe debug access level or state vulnerability in NVIDIA Hopper HGX 8-GPU from NVIDIA, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, without any action from a user. Affected NVIDIA Hopper HGX 8-GPU versions: HGX-22.10-1-rc67 (1.5.0); HGX-22.10-1-rc63 (1.4.0); HGX-22.10-1-rc59 (1.3.2), and others listed below. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.21% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.

Official description
NVIDIA 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.

The underlying weakness: Internal Asset Exposed to Unsafe Debug Access Level or State
The product uses physical debug or test interfaces with support for multiple access levels, but it assigns the wrong debug access level to an internal asset, providing unintended access to the asset from untrusted debug agents.
How developers prevent this class of flaw
- For security-sensitive assets accessible over debug/test interfaces, only allow trusted agents.
- Apply blinding or masking techniques in strategic areas.
- Add shielding or tamper-resistant protections to the device, which increases the difficulty and cost for accessing debug/test interfaces.
