Estado: ModificadaAlta (7.2)—

win32k.sys en los controladores de modo kernel de Microsoft Windows Vista SP1 y SP2, Windows Server 2008 Gold, Service Pack 2, R2 y R2 SP1, y el Windows 7 Gold y SP1 permite a usuarios locales conseguir privilegios a través de una aplicación diseñada que provoca una desreferencia a puntero nulo, una vulnerabilidad diferente a los CVE enumerados en MS11-054, también conocido como "Vulnerabilidad de desreferencia de puntero nulo en Win32k."

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).
