CVE-2024-44986
Estado: ModificadaAlta (7.8)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ipv6: se ha corregido un posible UAF en ip6_finish_output2() Si skb_expand_head() devuelve NULL, se ha liberado skb y también se podría haber liberado el dst/idev asociado. Necesitamos mantener rcu_read_lock() para asegurarnos de que el dst y el idev asociado estén activos.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 7.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.72%
- Percentil entre todas las CVEs puntuadas: 53
- 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).
