CVE-2025-68764

Estado: AplazadaAlta (7.8)—

In the Linux kernel, the following vulnerability has been resolved:

NFS: Automounted filesystems should inherit ro,noexec,nodev,sync flags

When a filesystem is being automounted, it needs to preserve the user-set superblock mount options, such as the "ro" flag.

CVSS

Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Puntuación base: 7.8

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 0.15%
Percentil entre todas las CVEs puntuadas: 4
Fecha de la puntuación: 6/10/2026

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).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

ExplotaciónT1068 Exploitation for Privilege Escalationprivilege escalation85 %
Impacto principalT1565.001 Stored Data Manipulationimpact75 %
Impacto secundarioT1059 Command and Scripting Interpreterexecution70 %

Acceso local sin interacción (AV:L/PR:L/UI:N) con permisos elevados. La falta de herencia de flags como 'ro' y 'noexec' en montajes NFS automáticos permite ejecutar código o modificar datos en filesystems que deberían estar protegidos.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
