The implementation unlinks an existing destination file and then recreates it using a path-based operation without the O_EXCL flag. A local attacker can exploit the window between the unlink and the subsequent creation to swap the path with a symbolic link, allowing them to redirect privileged writes to overwrite arbitrary system files.","state":0,"publishedAt":"2026-04-22T17:16:37.993+00:00","modifiedAt":"2026-06-17T10:40:27.013+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security@ubuntu.com · Secondary","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/uutils/coreutils/pull/10067","https://github.com/uutils/coreutils/releases/tag/0.6.0"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35355","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-367"],"productCriteria":["cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:37.993","lastModified":"2026-06-17T10:40:27.013"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
