The implementation uses String::from_utf8_lossy(), which replaces invalid UTF-8 byte sequences with the Unicode replacement character (U+FFFD). This behavior differs from GNU comm, which processes raw bytes and preserves the original input. This results in corrupted output when the utility is used to compare binary files or files using non-UTF-8 legacy encodings.","state":0,"publishedAt":"2026-04-22T17:16:36.76+00:00","modifiedAt":"2026-06-17T10:40:26.057+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security@ubuntu.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":3.3,"severity":"LOW"}],"references":["https://github.com/uutils/coreutils/issues/10192","https://github.com/uutils/coreutils/pull/10206","https://github.com/uutils/coreutils/releases/tag/0.6.0"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35346","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-176"],"productCriteria":["cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:36.760","lastModified":"2026-06-17T10:40:26.057"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
