On failure the stored id is negative, free_overlay_changeset()&#39;s &#34;if (ovcs-&gt;id)&#34; check passes, idr_remove() is called with a negative id and list_del() runs on ovcs-&gt;ovcs_list, which is not initialized until after the id allocation.

The rest of the function already copes with a partially-initialized ovcs, so the error path stays a plain goto err_free_ovcs.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>of/overlay: only treat a positive changeset id as registered</p> <p>of_overlay_fdt_apply() stores the idr_alloc() return value in ovcs-&gt;id before checking it.
