CVE-2021-1100

Estado: ModificadaMedia (5.5)—

NVIDIA vGPU software contains a vulnerability in the Virtual GPU Manager kernel mode driver (nvidia.ko), in which a pointer to a user-space buffer is not validated before it is dereferenced, which may lead to denial of service. This affects vGPU version 12.x (prior to 12.3), version 11.x (prior to 11.5) and version 8.x (prior 8.8).

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).
