CVE-2025-38422

Estado: ModificadaAlta (7.8)—

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

net: lan743x: Modify the EEPROM and OTP size for PCI1xxxx devices

Maximum OTP and EEPROM size for hearthstone PCI1xxxx devices are 8 Kb and 64 Kb respectively. Adjust max size definitions and return correct EEPROM length based on device. Also prevent out-of-bound read/write.

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: 0.18%
Percentil entre todas las CVEs puntuadas: 7
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
