The issue is related to insufficient input validation in the drm/amdgpu component of the Linux kernel. This can lead to a denial of service. The vulnerability is associated with the functions `amdgpu vm bo insert map()`, `amdgpu vm bo map()`, `amdgpu vm bo replace map()`, and `amdgpu vm bo clear mappings()` in the file drivers/gpu/drm/amd/amdgpu/amdgpu vm.c. The parameters of `amdgpu vm bo (map/replace map/clearing mappings)` are not validated clearly, which can be exploited to cause a denial of service.
