CVE-2022-50508

Estado: ModificadaAlta (7.1)—

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

wifi: mt76: mt76x0: fix oob access in mt76x0_phy_get_target_power

After 'commit ba45841ca5eb ("wifi: mt76: mt76x02: simplify struct mt76x02_rate_power")', mt76x02 relies on ht[0-7] rate_power data for vht mcs{0,7}, while it uses vth[0-1] rate_power for vht mcs {8,9}. Fix a possible out-of-bound access in mt76x0_phy_get_target_power routine.

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: 5/10/2026

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

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Impacto secundarioT1499.004 Application or System Exploitationimpact65 %

AV:L + PR:L sin UI indica escalada local. OOB access en kernel puede permitir ejecución de código o DoS; HIGH severity con C:H/A:H sugiere lecturas/corrupción de memoria.

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.
