The implementation mistakenly maps this string to the NUL character for both the -d (delimiter) and --output-delimiter options. This vulnerability can lead to silent data corruption or logic errors in automated scripts and data pipelines that process strings containing these characters, as the utility may unintentionally split or join data on NUL bytes rather than the intended literal characters."},{"lang":"es","value":"Un error lógico en la utilidad cut de uutils coreutils hace que el programa interprete incorrectamente la cadena literal de dos bytes ’’ (dos comillas simples) como un delimitador vacío. La implementación mapea erróneamente esta cadena al carácter NUL tanto para las opciones -d (delimitador) como --output-delimiter. Esta vulnerabilidad puede llevar a una corrupción silenciosa de datos o a errores lógicos en scripts automatizados y pipelines de datos que procesan cadenas que contienen estos caracteres, ya que la utilidad puede dividir o unir datos involuntariamente en bytes NUL en lugar de los caracteres literales previstos."}],"affected":[{"source":"security@ubuntu.com","affectedData":[{"vendor":"Uutils","product":"coreutils","defaultStatus":"unaffected","collectionURL":"https://github.com/uutils","packageName":"coreutils","platforms":["Linux","Unix","macOS"],"repo":"https://github.com/uutils/coreutils","versions":[{"version":"0","lessThan":"0.8.0","versionType":"semver","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security@ubuntu.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-22T16:53:51.376352Z","id":"CVE-2026-35380","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security@ubuntu.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*","versionEndExcluding":"0.8.0","matchCriteriaId":"2365DBBD-6F10-4651-8DA4-08AE79E14423"}]}]}],"references":[{"url":"https://github.com/uutils/coreutils/pull/11399","source":"security@ubuntu.com","tags":["Exploit","Issue Tracking","Patch"]},{"url":"https://github.com/uutils/coreutils/releases/tag/0.8.0","source":"security@ubuntu.com","tags":["Release Notes"]}]}
