{"id":"CVE-2026-35375","summary":"uutils coreutils split Local Data Integrity Issue via Lossy Filename Encoding","details":"A logic error in the split utility of uutils coreutils causes the corruption of output filenames when provided with non-UTF-8 prefix or suffix inputs. 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.","aliases":["GHSA-vx9m-xjwf-8cqm"],"modified":"2026-07-08T08:11:22.567852281Z","published":"2026-04-22T16:09:06.947Z","database_specific":{"cna_assigner":"canonical","cwe_ids":["CWE-176"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35375.json"},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35375.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35375"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/11397"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uutils/coreutils","events":[{"introduced":"0"},{"fixed":"c4093734e2ebe2efb7d65e216cd1444664bcf26a"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.8.0"}],"cpe":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"versions":["0.7.0","0.6.0","latest-commit","0.5.0","0.4.0","0.3.0","0.2.2","0.2.0","0.1.0","0.0.30-delete","0.0.30","0.0.29","0.0.28","0.0.27","0.0.26","0.0.25","0.0.24","0.0.23","0.0.22","0.0.21","0.0.20","0.0.19","0.0.18","0.0.17","0.0.16","0.0.15","0.0.14","0.0.13","0.0.12","0.0.9","0.0.8","0.0.7","0.0.6","0.0.5","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35375.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
