| CVE‑2022‑42290 | NVIDIA BMC contains a vulnerability in the SPX REST API, where an attacker with the required privileges can inject arbitrary shell commands, which may lead to code execution, denial of service, information disclosure, or data tampering. | 7.2 | AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2023‑0200 | NVIDIA DGX-2 contains a vulnerability in OFBD where a user with high privileges and a pre-conditioned heap can cause an access beyond a buffers end, which may lead to code execution, escalation of privileges, denial of service, and information disclosure. | 7.5 | AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
| CVE‑2023‑0201 | NVIDIA DGX-2 SBIOS contains a vulnerability in Bds, where a user with high privileges can cause a write beyond the bounds of an indexable resource, which may lead to code execution, denial of service, compromised integrity, and information disclosure. | 6.7 | AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H |
| CVE‑2023‑0202 | NVIDIA DGX A100 SBIOS contains a vulnerability where an attacker may modify arbitrary memory of SMRAM by exploiting the GenericSio and LegacySmmSredir SMM APIs. A successful exploit of this vulnerability may lead to denial of service, escalation of privileges, and information disclosure. |
7.5 | AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
| CVE‑2023‑0206 | NVIDIA DGX A100 SBIOS contains a vulnerability where an attacker may modify arbitrary memory of SMRAM by exploiting the NVME SMM API. A successful exploit of this vulnerability may lead to denial of service, escalation of privileges, and information disclosure. | 7.5 | AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
| CVE‑2023‑0207 | NVIDIA DGX-2 SBIOS contains a vulnerability where an attacker may modify the ServerSetup NVRAM variable at runtime by executing privileged code. A successful exploit of this vulnerability may lead to denial of service. | 7.5 | AV:L/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H |
The NVIDIA risk assessment is based on an average of risk across a diverse set of installed systems and may not represent the true risk to your local installation. NVIDIA recommends consulting a security or IT professional to evaluate the risk to your specific configuration.
