CVE-2024-56766
Estado: ModificadaAlta (7.8)—
In the Linux kernel, the following vulnerability has been resolved:
mtd: rawnand: fix double free in atmel_pmecc_create_user()
The "user" pointer was converted from being allocated with kzalloc() to being allocated by devm_kzalloc(). Calling kfree(user) will lead to a double free.
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: 0.22%
- Percentil entre todas las CVEs puntuadas: 12
- Fecha de la puntuación: 6/10/2026
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).
🎯 Técnicas ATT&CK
Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation85 % - Impacto principal
T1059Command and Scripting Interpreterexecution75 %
Acceso local (AV:L) sin interacción (UI:N) con privilegios de usuario (PR:L). Double free en kernel permite ejecutar código con privilegios elevados (C:H/I:H/A:H), escalando desde usuario a root.
Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
