Estado: AnalizadaAlta (7.1)—

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

wifi: mt76: Fix possible oob access in mt76_connac2_mac_write_txwi_80211()

Check frame length before accessing the mgmt fields in mt76_connac2_mac_write_txwi_80211 in order to avoid a possible oob access.

[fix check to also cover mgmt->u.action.u.addba_req.capab, correct Fixes tag]

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.

Vulnerabilidad local (AV:L, PR:L) en controlador wifi de kernel Linux que permite lectura/escritura fuera de límites (CWE-125 buffer over-read). Acceso local sin interacción de usuario sugiere T1068. Impactos: ejecución de código (T1059) o denegación de servicio (T1499.004).

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.
