CVE-2010-2549

Estado: ModificadaAlta (7.2)—💥 Exploit

Vulnerabilidad de uso después de la liberación (use-after-free) en Microsoft Windows Vista y Server 2008 permite a usuarios locales causar una denegación de servicio (caída del sistema) mediante el uso de un gran número de llamadas a la función NtUserCheckAccessForIntegrityLevel para desencadenar un fallo en la función LockProcessByClientId, lo que provoca que un objeto proceso sea eliminado cuando todavía está en uso.

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.
