CVE-2025-38342
Estado: ModificadaAlta (7.1)—
In the Linux kernel, the following vulnerability has been resolved:
software node: Correct a OOB check in software_node_get_reference_args()
software_node_get_reference_args() wants to get @index-th element, so the property value requires at least '(index + 1) * sizeof(*ref)' bytes but that can not be guaranteed by current OOB check, and may cause OOB for malformed property.
Fix by using as OOB check '((index + 1) * sizeof(*ref) > prop->length)'.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H
- Puntuación base: 7.1
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).
