CVE-2025-38479

Estado: AnalizadaAlta (7.8)—

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

dmaengine: fsl-edma: free irq correctly in remove path

Detalles técnicos trazas, registros y código del informe original

Add fsl_edma->txirq/errirq check to avoid below warning because no
errirq at i.MX9 platform. Otherwise there will be kernel dump:

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: 0.28%
Percentil entre todas las CVEs puntuadas: 18
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.
