{"id":"UBUNTU-CVE-2026-35375","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.","modified":"2026-05-14T14:41:44.504154Z","published":"2026-04-22T17:16:00Z","upstream":["CVE-2026-35375"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35375"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35375"},{"type":"REPORT","url":"https://github.com/uutils/coreutils/pull/11397"}],"affected":[{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-coreutils@0.0.24-2?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.20-1","0.0.22-1","0.0.23-1","0.0.23-2","0.0.23-3","0.0.24-1","0.0.24-2"],"ecosystem_specific":{"binaries":[{"binary_name":"rust-coreutils","binary_version":"0.0.24-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35375.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rust-coreutils@0.2.2-0ubuntu2.1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.30-1","0.0.30-2","0.0.30-2ubuntu2","0.1.0-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu2","0.1.0+git20250711.2ba3a33-0ubuntu3","0.1.0+git20250711.2ba3a33-0ubuntu4","0.1.0+git20250801.cf79675-0ubuntu1","0.1.0+git20250813.4af2a84-0ubuntu2","0.1.0+git20250813.4af2a84-0ubuntu4","0.1.0+git20250813.4af2a84-0ubuntu6","0.1.0+git20250813.4af2a84-0ubuntu7","0.2.2-0ubuntu1","0.2.2-0ubuntu2","0.2.2-0ubuntu2.1"],"ecosystem_specific":{"binaries":[{"binary_name":"rust-coreutils","binary_version":"0.2.2-0ubuntu2.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"Ubuntu","score":"medium"}]}
