CVE-2019-16746

Estado: ModificadaCrítica (9.8)—💥 PoC

Se detectó un problema en el archivo net/wireless/nl80211.c en el kernel de Linux versiones hasta 5.2.17. No comprueba la longitud de los elementos variables en un beacon head, lo que provoca un desbordamiento del búfer.

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).

💥 Exploits públicos

Hay código de explotación o plantillas de detección públicos. No es lo mismo que explotación activa confirmada (KEV), pero aumenta el riesgo: parchee con prioridad.

⚠️ Las pruebas de concepto de GitHub no están verificadas: algunas son falsas o contienen malware. No las ejecute nunca fuera de un laboratorio aislado.
