La función ipv6_getsockopt_sticky en net/ipv6/ipv6_sockglue.c en el núcleo de Linux anterior a 2.6.20.2 permite a usuarios locales leer memoria del núcleo de su elección mediante determinadas llamadas getsockopt que disparan una referencia a NULL.

CVSS

Puntuación base: 7.2
Versión: 2.0
Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C

Probabilidad de explotación (EPSS)

Probabilidad de explotación en los próximos 30 días: 1.14 %
Percentil entre todas las CVEs puntuadas: 66
Fecha de la puntuación: 21/10/2026

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.
