CVE-2025-38317

Estado: ModificadaAlta (7.8)—

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

wifi: ath12k: Fix buffer overflow in debugfs

If the user tries to write more than 32 bytes then it results in memory corruption. Fortunately, this is debugfs so it's limited to root users.

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: 0.19%
Percentil entre todas las CVEs puntuadas: 8
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).
