However, the implementation simply breaks\nfrom a switch statement and leaks uninitialized return code `rc' (if the\nfirst section is a security one) or the previous section's `rc'.\n\nFix it by really skipping a loop with `continue'. For consistency and\nreadability, also do the same for the default case.","state":0,"publishedAt":"2026-09-25T10:22:32.244+00:00","modifiedAt":"2026-10-19T09:10:33.668+00:00","affected":[{"ecosystem":"Vendor
