The implementation utilizes to_string_lossy() when constructing chunk filenames, which automatically rewrites invalid byte sequences into the UTF-8 replacement character (U+FFFD). This behavior diverges from GNU split, which preserves raw pathname bytes intact. In environments utilizing non-UTF-8 encodings, this vulnerability leads to the creation of files with incorrect names, potentially causing filename collisions, broken automation, or the misdirection of output data.","state":0,"publishedAt":"2026-04-22T16:09:06.947+00:00","modifiedAt":"2026-04-22T17:17:35.677+00:00","affected":[{"ecosystem":"https://github.com/uutils","name":"coreutils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Uutils\",\n                    \"product\": \"coreutils\",\n                    \"platforms\": [\n                        \"Linux\",\n                        \"Unix\",\n                        \"macOS\"\n                    ],\n                    \"collectionURL\": \"https://github.com/uutils\",\n                    \"packageName\": \"coreutils\",\n                    \"repo\": \"https://github.com/uutils/coreutils\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"lessThan\": \"0.8.0\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":3.3,"severity":"LOW"}],"references":["https://github.com/uutils/coreutils/pull/11397","https://github.com/uutils/coreutils/releases/tag/0.8.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-35375","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-35375","identifiers":["CVE-2026-35375"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
