  "details": "In the Linux kernel, the following vulnerability has been resolved:  of/overlay: only treat a positive changeset id as registered  of_overlay_fdt_apply() stores the idr_alloc() return value in ovcs-\u003eid before checking it. On failure the stored id is negative, free_overlay_changeset()'s \"if (ovcs-\u003eid)\" check passes, idr_remove() is called with a negative id and list_del() runs on ovcs-\u003eovcs_list, which is not initialized until after the id allocation. An allocation failure at that point dereferences NULL.  Make free_overlay_changeset() treat only a strict-positive id as registered. The rest of the function already copes with a partially-initialized ovcs, so the error path stays a plain goto err_free_ovcs.",
