CVE-2019-5688

Estado: ModificadaMedia (6.7)—💥 PoC

NVIDIA NVFlash, NVUFlash Tool prior to v5.588.0 and GPUModeSwitch Tool prior to 2019-11, NVIDIA kernel mode driver (nvflash.sys, nvflsh32.sys, and nvflsh64.sys) contains a vulnerability in which authenticated users with administrative privileges can gain access to device memory and registers of other devices not managed by NVIDIA, which may lead to escalation of privileges, information disclosure, or denial of service.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
