CVE-2026-64111

Estado: AnalizadaAlta (7.1)—

In the Linux kernel, the following vulnerability has been resolved:

lsm: hold cred_guard_mutex for lsm_set_self_attr()

Just as proc_pid_attr_write() already does before calling the LSM hook. This only matters for SELinux and AppArmor which check whether the process is being ptraced and if so, whether to allow the transition.

CVSS

Probabilidad de explotación (EPSS)

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.

Vulnerabilidad local en kernel Linux que afecta a procesos con privilegios (PR:L), sin interacción del usuario. El defecto en lsm_set_self_attr() permite evasión de controles de SELinux/AppArmor en ptrace, resultando en escalada de privilegios (C:H, I:H).

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.
