In the Linux kernel, the following vulnerability has been resolved:
drm/xe: Fix bo leak in xe_dma_buf_init_obj() on allocation failure
When drm_gpuvm_resv_object_alloc() fails, the pre-allocated storage bo
is not freed. Add xe_bo_free(storage) before returning the error.
xe_dma_buf_init_obj() calls xe_bo_init_locked(), which frees the bo on
error. Therefore, xe_dma_buf_init_obj() must also free the bo on its own
error paths. Otherwise, since xe_gem_prime_import() cannot distinguish
whether the failure originated from xe_dma_buf_init_obj() or from
xe_bo_init_locked(), it cannot safely decide whether the bo should be
freed.
Add comments documenting the ownership semantics: on success, ownership
of storage is transferred to the returned drm_gem_object; on failure,
storage is freed before returning.
v2: Add comments to explain the free logic.
