CVE-2024-20137

Estado: AplazadaAlta (7.5)—

In wlan driver, there is a possible client disconnection due to improper handling of exceptional conditions. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00384543; Issue ID: MSV-1727.

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.
