CVE-2017-7374
Vulnerabilidad de uso después de liberación de memoria en fs/crypto/ en el kernel de Linux en versiones anteriores a 4.10.7 permite a usuarios locales provocar una denegación de servicio (referencia a puntero NULL) o posiblemente obtener privilegios revocando el llavero de claves utilizado para cifrado ext4, f2fs o ubifs, provocando que los objetos de transformación criptográfica sean liberados prematuramente.
CVSS
- Puntuación base
- 7.8
- Versión
- 3.1
- Vector
- CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días
- 0.80 %
- Percentil entre todas las CVEs puntuadas
- 56
- Fecha de la puntuación
- 20/10/2026
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.
