The implementation enforces UTF-8 encoding and utilizes expect(), causing an immediate crash when encountering valid but non-UTF-8 paths. This diverges from GNU sort, which treats filenames as raw bytes. A local attacker can exploit this to crash the utility and disrupt automated pipelines."}], "lastModified": "2026-04-24T18:57:20.927", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:uutils:coreutils:-:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "4A9AF9E4-E17C-48AD-8051-B49998618839"}], "operator": "OR"}]}], "sourceIdentifier": "security@ubuntu.com"}
