CVE-2024-35962
Estado: ModificadaMedia (5.5)—
Detalles técnicos trazas, registros y código del informe original
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: validación completa de la entrada del usuario En mi confirmación reciente, omití que los controladores do_replace() usan copy_from_sockptr() (que arreglé), seguido de llamadas inseguras copy_from_sockptr_offset(). En todas las funciones, podemos realizar la validación @optlen incluso antes de llamar a xt_alloc_table_info() con la siguiente comprobación: if ((u64)optlen < (u64)tmp.size + sizeof(tmp)) return -EINVAL;
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: 0.24%
- Percentil entre todas las CVEs puntuadas: 14
- 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).
