Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag
Otherwise after the GTT bo is released, the GTT and gart space is freed
but amdgpu_ttm_backend_unbind will not clear the gart page table entry
and leave valid mapping entry pointing to the stale system page. Then
if GPU access the gart address mistakely, it will read undefined value
instead page fault, harder to debug and reproduce the real issue.
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag
The Linux kernel CVE team has assigned CVE-2024-35817 to this issue.
Upstream advisory:
https://lore.kernel.org/linux-cve-announce/2024051743-CVE-2024-35817-d29b@gregkh/T
Отчет
This vulnerability is rated as Low impact because exploitation requires local access on systems equipped with AMD GPU hardware, and the uncleaned GART page table mappings primarily cause driver instability or a denial of service rather than privilege escalation. Standard Red Hat Enterprise Linux server deployments typically run headlessly or on virtualized infrastructure without physical AMD GPUs, significantly limiting exposure. Systems operating without AMD graphics adapters do not load the affected driver and remain unaffected.
