CVE-2024-35936
Estado: ModificadaMedia (5.5)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: maneja el error de búsqueda del árbol de fragmentos en btrfs_relocate_sys_chunks() El caso no controlado en el bucle btrfs_relocate_sys_chunks() es una corrupción, ya que solo podría ser causado por dos condiciones imposibles: - al principio el La clave de búsqueda está configurada para buscar un elemento del árbol de fragmentos, con desplazamiento -1, esta es una búsqueda inexacta y la clave->desplazamiento contendrá el desplazamiento correcto tras una búsqueda exitosa, un elemento de árbol de fragmentos válido no puede tener un desplazamiento -1 - después de la primera búsqueda exitosa, found_key corresponde a un elemento fragmentado, el desplazamiento se reduce en 1 antes del siguiente ciclo, es imposible encontrar un elemento fragmentado allí debido a restricciones de alineación y tamaño
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: 0.23%
- Percentil entre todas las CVEs puntuadas: 13
- 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).
