CVE-2026-46230
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/vcn3: Prevent OOB reads when parsing dec msg
Check bounds against the end of the BO whenever we access the msg.
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: 0.12%
- Percentil entre todas las CVEs puntuadas: 2
- 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.
- Explotación
T1068Exploitation for Privilege Escalationprivilege escalation75 % - Impacto principal
T1005Data from Local Systemcollection70 % - Impacto secundario
T1499.004Application or System Exploitationimpact60 %
Vulnerabilidad local (AV:L/PR:L) sin interacción (UI:N) en kernel Linux; OOB read permite lectura de memoria kernel (confidencialidad alta) y DoS (disponibilidad). Privilegios requeridos descartan escalada única.
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.
