CVE-2026-8936

Estado: Pendiente de análisisAlta (8.2)—

Fixed a VM panic caused by unbounded recursion in the grpcfuse kernel module when a container created deeply nested directories on a bind-mounted host folder and triggered a dentry invalidation event. This issue has been fixed in Docker Desktop 4.76.0.

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).

🎯 Técnicas ATT&CK

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

Acceso local (AV:L) con privilegios (PR:L) sin UI requerida; escalada de privilegios a través del pánico de VM. El CWE-674 (recursión no acotada) causa DoS local confirmado en descripción.

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.
