CVE-2022-26522

Estado: Pendiente de análisisAlta (7.8)—

The socket connection handler in aswArPot.sys in the Avast and AVG Windows Anti Rootkit driver before 22.1 allows local attackers to execute arbitrary code in kernel mode or cause a denial of service (memory corruption and OS crash) due to a double fetch vulnerability at aswArPot+0xc4a3.

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.

AV:L/PR:L sin UI permite escalada local; double fetch en driver kernel permite ejecución arbitraria de código o DoS por 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.
