When copying with the -p (preserve) flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining original privileged bits, creating unexpected privileged executables that violate local security policies. This differs from GNU cp, which clears these bits when ownership cannot be preserved."}],"references":[{"url":"https://github.com/uutils/coreutils/issues/9750","tags":["issue-tracking"]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"LOW","integrityImpact":"HIGH","availabilityImpact":"LOW","baseSeverity":"MEDIUM","baseScore":6.6,"vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:H/A:L"}}],"credits":[{"lang":"en","value":"Zellic","type":"finder"}],"source":{"discovery":"EXTERNAL"},"providerMetadata":{"orgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","shortName":"canonical","dateUpdated":"2026-04-22T16:08:02.526Z"}},"adp":[{"references":[{"url":"https://github.com/uutils/coreutils/issues/9750","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-22T17:56:50.879133Z","id":"CVE-2026-35350","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-04-22T17:58:14.456Z"}}]}}
