{"id":"GHSA-vx9m-xjwf-8cqm","summary":"uutils coreutils has an Improper Handling of Unicode Encoding Issue","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":["CVE-2026-35375"],"modified":"2026-05-05T16:26:36.493823Z","published":"2026-04-22T18:31:46Z","database_specific":{"cwe_ids":["CWE-176"],"severity":"LOW","github_reviewed":true,"github_reviewed_at":"2026-04-30T17:56:29Z","nvd_published_at":"2026-04-22T17:16:42Z"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35375"},{"type":"WEB","url":"https://github.com/uutils/coreutils/pull/11397"},{"type":"WEB","url":"https://github.com/uutils/coreutils/commit/d2b9550fe821a9a10bf0cec057509211357363f1"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"https://github.com/uutils/coreutils/releases/tag/0.8.0"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-vx9m-xjwf-8cqm/GHSA-vx9m-xjwf-8cqm.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
