CVE-2022-49969

Estado: AnalizadaAlta (7.8)—

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

drm/amd/display: clear optc underflow before turn off odm clock

[Why] After ODM clock off, optc underflow bit will be kept there always and clear not work. We need to clear that before clock off.

[How] Clear that if have when clock off.

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 indica escalada local; underflow en display puede causar DoS a nivel de kernel (application hang).

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.
