CVE-2025-22112

Estado: AnalizadaAlta (7.1)—

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

eth: bnxt: fix out-of-range access of vnic_info array

The bnxt_queue_{start | stop}() access vnic_info as much as allocated, which indicates bp->nr_vnics. So, it should not reach bp->vnic_info[bp->nr_vnics].

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 de usuario a arreglo fuera de rango en kernel Linux (CWE-125). Permite escalada de privilegios y ejecución de código o DoS en el kernel.

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.
