CVE-2025-38367

Estado: ModificadaAlta (7.8)—

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

LoongArch: KVM: Avoid overflow with array index

The variable index is modified and reused as array index when modify register EIOINTC_ENABLE. There will be array index overflow problem.

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.

Acceso local (AV:L) sin interacción (UI:N) con privs (PR:L) en kernel: escalada. Overflow en índice permite ejecución arbitraria o DoS; KVM context sugiere posible DoS en VM.

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.
