FKIE_CVE-2026-80541
Vulnerability from fkie_nvd - Published: 2026-08-26 15:17 - Updated: 2026-08-27 06:17
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: validate GEM_CREATE domain combinations
AMDGPU_GEM_CREATE checked domain bits against AMDGPU_GEM_DOMAIN_MASK,
but did not validate domain combinations. Userspace could combine
CPU|GTT|VRAM with DOORBELL, GDS, GWS, or OA, making
amdgpu_bo_placement_from_domain() exceed AMDGPU_BO_MAX_PLACEMENTS and
hit BUG_ON().
Allow combinations only within CPU/GTT/VRAM, and require non-CPU/GTT/
VRAM domains to be specified one at a time. Return -EINVAL for invalid
combinations in amdgpu_gem_create_ioctl().
v2: Rename helper from amdgpu_gem_domain_valid() to
amdgpu_gem_are_domains_valid() (Christian)
(cherry picked from commit db39852d0c39843cb02048dfb47e4b8c703e9080)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
