CVE-2018-3990

Estado: ModificadaAlta (7.8)—

An exploitable pool corruption vulnerability exists in the 0x8200E804 IOCTL handler functionality of WIBU-SYSTEMS WibuKey.sys Version 6.40 (Build 2400). A specially crafted IRP request can cause a buffer overflow, resulting in kernel memory corruption and, potentially, privilege escalation. An attacker can send an IRP request to trigger this vulnerability.

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).
