CVE-2024-36017
Estado: AnalizadaMedia (5.5)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: rtnetlink: Validación correcta del atributo IFLA_VF_VLAN_LIST anidado. Se supone que cada atributo dentro de un IFLA_VF_VLAN_LIST anidado es una estructura ifla_vf_vlan_info, por lo que el tamaño de dicho atributo debe ser al menos de sizeof(struct ifla_vf_vlan_info), que es de 14 bytes. La validación de tamaño actual en do_setvfinfo es contra NLA_HDRLEN (4 bytes), que es menor que sizeof(struct ifla_vf_vlan_info), por lo que esta validación no es suficiente y un atributo demasiado pequeño podría convertirse en una estructura ifla_vf_vlan_info, esto podría resultar en un acceso de lectura fuera de banda al acceder a la entrada guardada (transmitida) en ivvl.
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: 0.25%
- Percentil entre todas las CVEs puntuadas: 15
- 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).
