The reported path was manually inspected before sending this fix.\n\nCompile-tested with CONFIG_SUNGEM=y. Runtime testing was not performed\nbecause no sungem hardware is available.","state":0,"publishedAt":"2026-08-15T05:56:30.225+00:00","modifiedAt":"2026-10-16T18:55:22.076+00:00","affected":[{"ecosystem":"Vendor
