Description

The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input within the amdgpu_vm_bo_insert_map(), amdgpu_vm_bo_map(), amdgpu_vm_bo_replace_map(), and amdgpu_vm_bo_clear_mappings() functions in drivers/gpu/drm/amd/amdgpu/amdgpu_vm.c. A local user can pass specially crafted input to the driver and perform a denial of service (DoS) attack.

Mitigation
