{"cve":"CVE-2026-35375","nvd":{"published":"2026-04-22T17:16:42.293","modified":"2026-10-26T22:10:00.163","status":"Analyzed","description":"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.","cvss_v4":null,"cvss_v3":{"version":"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},"cwes":["CWE-176"],"references":["https://github.com/uutils/coreutils/pull/11397","https://github.com/uutils/coreutils/releases/tag/0.8.0"],"products":["uutils:coreutils"],"source":"nvd","synced_at":"2026-10-26T22:26:44.656832877+00:00"},"epss":{"cve":"CVE-2026-35375","score":0.00143,"percentile":0.03577,"date":"2026-10-26"},"kev":null,"osv":[{"id":"GHSA-vx9m-xjwf-8cqm","url":"https://osv.dev/vulnerability/GHSA-vx9m-xjwf-8cqm","summary":"uutils coreutils has an Improper Handling of Unicode Encoding Issue","modified":"2026-05-05T16:26:36.493823Z","packages":[{"ecosystem":"crates.io","name":"coreutils","purl":"pkg:cargo/coreutils","ranges":["<0.8.0"],"fixed":["0.8.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
