CVE-2024-56598

Estado: ModificadaAlta (7.8)—

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

jfs: array-index-out-of-bounds fix in dtReadFirst

The value of stbl can be sometimes out of bounds due to a bad filesystem. Added a check with appopriate return of error code in that case.

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: 0.26%
Percentil entre todas las CVEs puntuadas: 16
Fecha de la puntuación: 5/10/2026

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.

AV:L sin UI:N y PR:L indica escalada de privilegios local (T1068). Array-index-out-of-bounds en kernel JFS puede permitir ejecución de código o DoS. Confianza moderada por falta de detalles sobre explotabilidad real.

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.
