What is CVE-2024-35817?
CVE-2024-35817 is a high-severity vulnerability in Linux kernel, published on 17 May 2024. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
