CVE-2010-2693

Estado: ModificadaAlta (7.2)—💥 Exploit

FreeBSD 7.1 through 8.1-PRERELEASE does not copy the read-only flag when creating a duplicate mbuf buffer reference, which allows local users to cause a denial of service (system file corruption) and gain privileges via the sendfile system call.

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.
