CVE-2023-53819

Estado: AplazadaAlta (7.8)—

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

amdgpu: validate offset_in_bo of drm_amdgpu_gem_va

This is motivated by OOB access in amdgpu_vm_update_range when offset_in_bo+map_size overflows.

v2: keep the validations in amdgpu_vm_bo_map v3: add the validations to amdgpu_vm_bo_map/amdgpu_vm_bo_replace_map rather than to amdgpu_gem_va_ioctl

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.

Vulnerabilidad local (AV:L, PR:L) sin interacción de usuario que permite acceso a memoria fuera de límites (OOB) mediante manipulación de parámetros offset_in_bo. El overflow en amdgpu_vm_update_range puede leer datos del kernel (C:H) e incluso modificarlos (I:H), tipificando escalada local y lectur

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.
