CVE-2022-31599

Estado: ModificadaAlta (8.2)—

NVIDIA DGX A100 contains a vulnerability in SBIOS in the Ofbd, where a local user with elevated privileges can cause access to an uninitialized pointer, which may lead to code execution, escalation of privileges, denial of service, and information disclosure. The scope of impact can extend to other components.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
