CVE-2022-31600

Estado: ModificadaAlta (8.2)—

NVIDIA DGX A100 contains a vulnerability in SBIOS in the SmmCore, where a user with high privileges can chain another vulnerability to this vulnerability, causing an integer overflow, possibly leading to code execution, escalation of privileges, denial of service, compromised integrity, and information disclosure. The scope of impact can extend to other components.
