While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directories caused by full disks or read-only file systems. This can lead to silent data corruption in backup or migration scripts, as the utility may report a successful operation even when the destination file contains old or garbage data."}],"affected":[{"source":"security@ubuntu.com","affectedData":[{"vendor":"Uutils","product":"coreutils","defaultStatus":"affected","collectionURL":"https://github.com/uutils","packageName":"coreutils","platforms":["Linux","Unix","macOS"],"repo":"https://github.com/uutils/coreutils"}]}],"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:L/A:N","baseScore":3.3,"baseSeverity":"LOW","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":1.8,"impactScore":1.4}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-04-22T18:04:37.730982Z","id":"CVE-2026-35344","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-252"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:uutils:coreutils:-:*:*:*:*:rust:*:*","matchCriteriaId":"4A9AF9E4-E17C-48AD-8051-B49998618839"}]}]}],"references":[{"url":"https://github.com/uutils/coreutils/issues/9745","source":"security@ubuntu.com","tags":["Issue Tracking"]}]}
