It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-35375 exists.\n\nAffected packages and fixed versions:\n- coreutils (crates.io): affected all versions; fixed in 0.8.0\n- coreutils (crates.io): affected all versions; fixed in 0.8.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-35375/ (Markdown: https://insights.sbomify.com/CVE-2026-35375/index.md)","id":"CVE-2026-35375","markdown":"https://insights.sbomify.com/CVE-2026-35375/index.md","name":"CVE-2026-35375","record":{"aliases":["DEBIAN-CVE-2026-35375","GHSA-vx9m-xjwf-8cqm","UBUNTU-CVE-2026-35375"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["data_modify","other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"coreutils split utility","requires_auth":"low_privilege","summary":"Attackers can corrupt output filenames in split utility via non-UTF-8 inputs, causing data misdirection or collisions in non-UTF-8 environments.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"coreutils","vendor":"uutils"}],"cvss":{"score":3.3,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-176","name":"Improper Handling of Unicode Encoding"}],"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.

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.","ecosystems":["crates.io"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"uutils coreutils split Local Data Integrity Issue via Lossy Filename Encoding","id":"CVE-2026-35375","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"other","year":"2026"},"n_packages":2,"n_references":2,"next":{"headline":"uutils coreutils chcon Security Bypass and Mandatory Access Control (MAC) Inconsistency via TOCTOU Race Condition","id":"CVE-2026-35376"},"packages":[{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"coreutils","purl":null,"source":"GHSA-vx9m-xjwf-8cqm"},{"ecosystem":"crates.io","fixed":["0.8.0"],"introduced":["0"],"last_affected":[],"package":"coreutils","purl":"pkg:cargo/coreutils","source":"GHSA-vx9m-xjwf-8cqm"}],"prev":{"headline":"uutils coreutils split Arbitrary File Truncation via Time-of-Check to Time-of-Use (TOCTOU) Race Condition","id":"CVE-2026-35374"},"products":["coreutils"],"published":"2026-04-22","related":[{"cvss_score":7.3,"headline":"uutils coreutils chmod Path Traversal Bypass of --preserve-root","id":"CVE-2026-35338","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.2,"headline":"uutils coreutils chroot Local Privilege Escalation and chroot Escape in via Name Service Switch (NSS) Injection","id":"CVE-2026-35368","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7.1,"headline":"uutils coreutils mkfifo Unauthorized Permission Change on Existing Files","id":"CVE-2026-35341","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":7,"headline":"uutils coreutils mkfifo Privilege Escalation via TOCTOU Race Condition","id":"CVE-2026-35352","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.7,"headline":"uutils coreutils Path-Based Safety Bypass with --preserve-root","id":"CVE-2026-35349","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.6,"headline":"uutils coreutils cp Unexpected Privileged Executable Creation with -p","id":"CVE-2026-35350","kev_date_added":null,"published":"2026-04-22"},{"cvss_score":6.6,"headline":"uutils coreutils mv Denial of Service and Data Duplication via Improper Symlink Expansion","id":"CVE-2026-35365","kev_date_added":null,"published":"2026-04-22"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-22","vendors":["Uutils"]},"summary":"Attackers can corrupt output filenames in split utility via non-UTF-8 inputs, causing data misdirection or collisions in non-UTF-8 environments.","url":"https://insights.sbomify.com/CVE-2026-35375/"}
