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."}], "lastModified": "2026-05-04T19:13:37.293", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "2365DBBD-6F10-4651-8DA4-08AE79E14423", "versionEndExcluding": "0.8.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@ubuntu.com"}
