# CVE-2026-35375

## Summary

- **CVE ID:** CVE-2026-35375
- **Severity:** LOW
- **CVSS Score:** 3.3 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N)
- **CWE:** CWE-176
- **Published:** Apr 22, 2026
- **Last Modified:** Apr 22, 2026

## 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.
