The implementation previously only honored the \"no-dereference\" intent if the --force (overwrite) mode was also enabled. This flaw causes ln to follow a symbolic link that points to a directory and create new links inside that target directory instead of treating the symbolic link itself as the destination. In environments where a privileged user or system script uses ln -n to update a symlink, a local attacker could manipulate existing symbolic links to redirect file creation into sensitive directories, potentially leading to unauthorized file creation or system misconfiguration."}],"references":[{"url":"https://github.com/uutils/coreutils/pull/11253","tags":["issue-tracking","patch"]},{"url":"https://github.com/uutils/coreutils/releases/tag/0.8.0","tags":["vendor-advisory"]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE","baseSeverity":"MEDIUM","baseScore":5,"vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:N/I:H/A:N"}}],"credits":[{"lang":"en","value":"Zellic","type":"finder"}],"source":{"discovery":"EXTERNAL"},"providerMetadata":{"orgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","shortName":"canonical","dateUpdated":"2026-04-22T16:08:58.696Z"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-04-22T17:21:07.778700Z","id":"CVE-2026-35372","options":[{"Exploitation":"none"},{"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":"2026-04-22T17:21:15.165Z"}}]}}
