CVE-2024-36929
Estado: ModificadaMedia (5.5)—
En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: core: rechazar skb_copy(_expand) para fraglist GSO skbs Los skbs SKB_GSO_FRAGLIST no deben linealizarse; de lo contrario, dejarán de ser válidos. Devuelve NULL si dicho skb se pasa a skb_copy o skb_copy_expand, para evitar un bloqueo en una posible llamada posterior a skb_gso_segment.
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: 0.90%
- Percentil entre todas las CVEs puntuadas: 59
- 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).
