CVE-2008-5736

Estado: ModificadaAlta (7.2)—💥 Exploit

Multiple unspecified vulnerabilities in FreeBSD 6 before 6.4-STABLE, 6.3 before 6.3-RELEASE-p7, 6.4 before 6.4-RELEASE-p1, 7.0 before 7.0-RELEASE-p7, 7.1 before 7.1-RC2, and 7 before 7.1-PRERELEASE allow local users to gain privileges via unknown attack vectors related to function pointers that are "not properly initialized" for (1) netgraph sockets and (2) bluetooth sockets.

CVSS

Versión: 2.0
Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
Puntuación base: 7.2

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.20%
Percentil entre todas las CVEs puntuadas: 67
Fecha de la puntuación: 7/10/2026

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.
