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."}],"references":[{"url":"https://github.com/uutils/coreutils/pull/11397","tags":["issue-tracking","patch"]},{"url":"https://github.com/uutils/coreutils/releases/tag/0.8.0","tags":["vendor-advisory"]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE","baseSeverity":"LOW","baseScore":3.3,"vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}}],"credits":[{"lang":"en","value":"Zellic","type":"finder"}],"source":{"discovery":"EXTERNAL"},"providerMetadata":{"orgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","shortName":"canonical","dateUpdated":"2026-04-22T16:09:06.947Z"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-22T17:17:33.122757Z","id":"CVE-2026-35375","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-22T17:17:35.677Z"}}]}}
