CVE-2022-25479

Estado: ModificadaMedia (5.5)—💥 PoC

Vulnerability in Realtek RtsPer driver for PCIe Card Reader (RtsPer.sys) before 10.0.22000.21355 and Realtek RtsUer driver for USB Card Reader (RtsUer.sys) before 10.0.22000.31274 allows for the leakage of kernel memory from both the stack and the heap.

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.
