## Description

In the Linux kernel, the following vulnerability has been resolved:  accel/amdxdna: Fix use-after-free in amdxdna_gem_dmabuf_mmap()  When vm_insert_pages() fails, the error path calls vma->vm_ops->close(vma) which internally calls drm_gem_vm_close() → drm_gem_object_put(), releasing the GEM object reference acquired at the start of the function. However, the close_vma label then falls through to put_obj, which calls drm_gem_object_put() a second time on the same object.  If the first put releases the last reference, the object is freed and the second put accesses freed memory, causing a use-after-free.  Fix by returning directly from close_vma instead of falling through to put_obj, since the close handler already performs all necessary cleanup including the object put.
