La función mq_notify en el kernel de Linux hasta versión 4.11.9 no se ajusta el puntero sock a NULL al ingresar a la lógica de reintento. Durante un cierre de espacio de usuario de un socket Netlink, permite que los atacantes causen una denegación de servicio (uso de memoria previamente liberada) o posiblemente tengan otro impacto no especificado.

CVSS

Puntuación base: 7.8
Versión: 3.1
Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 3.82 %
Percentil entre todas las CVEs puntuadas: 90
Fecha de la puntuación: 20/10/2026

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).

Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.
