CVE-2024-35817

CVE-2024-35817 is a Linux kernel issue affecting the AMDGPU driver (drm/amdgpu). The root cause is that after GTT/ Gart space is freed, amdgpu_ttm_backend_unbind does not clear the GTT page table entry, leaving a valid mapping to a stale system page. If the GPU accesses the stale GART address, it...
