CVE-2024-26697
Estado: ModificadaMedia (5.5)—
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nilfs2: corrige la corrupción de datos en la recuperación de bloques dsync para tamaños de bloques pequeños La función auxiliar nilfs_recovery_copy_block() de nilfs_recovery_dsync_blocks(), que recupera datos de los registros creados por escrituras de sincronización de datos durante un montaje después un apagado incorrecto calcula incorrectamente el desplazamiento en la página al copiar los datos de reparación en la memoria caché de la página del archivo.
Leer descripción completaMostrar menos
En entornos donde el tamaño del bloque es menor que el tamaño de la página, esta falla puede causar corrupción de datos y pérdida de bytes de memoria no inicializados durante el proceso de recuperación. Solucione estos problemas corrigiendo este cálculo de desplazamiento de bytes en la página.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 5.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.26%
- Percentil entre todas las CVEs puntuadas: 17
- Fecha de la puntuación: 8/10/2026
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).
