Summary
CVE-2021-47144 is a vulnerability affecting the Linux kernel that has been addressed. In the amdgpu driver, a refcount leak occurred due to the gem object rfb->base.obj[0] being retrieved based on num_planes but not released accordingly in amdgpu_fbdev_destroy. This could potentially lead to memory leaks and other unintended consequences. The issue has been resolved by ensuring that rfb->base.obj[0] is put back correctly based on num_planes in the destroy function.
