"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nof/overlay: only treat a positive changeset id as registered\n\nof_overlay_fdt_apply() stores the idr_alloc() return value in\novcs->id before checking it. On failure the stored id is negative,\nfree_overlay_changeset()'s \"if (ovcs->id)\" check passes, idr_remove()\nis called with a negative id and list_del() runs on ovcs->ovcs_list,\nwhich is not initialized until after the id allocation. An allocation\nfailure at that point dereferences NULL.\n\nMake free_overlay_changeset() treat only a strict-positive id as\nregistered. The rest of the function already copes with a\npartially-initialized ovcs, so the error path stays a plain\ngoto err_free_ovcs."
