We were just lucky so far since we used only a couple of PDIs\nand remained within the PDI array bounds.\n\nA Fixes: tag is not provided since there are no known platforms where\nthe out-of-bounds would be accessed, and the initial code had problems\nas well.\n\nA follow-up patch completely removes this useless offset.","state":0,"publishedAt":"2024-06-21T10:18:24.244+00:00","modifiedAt":"2026-10-15T00:43:50.068+00:00","affected":[{"ecosystem":"Vendor
