The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link between these two operations. This redirects the chmod call to an arbitrary file, potentially enabling privilege escalation if the utility is run with elevated privileges.","state":0,"publishedAt":"2026-04-22T17:16:37.597+00:00","modifiedAt":"2026-10-26T21:10:00.17+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:H/I:H/A:H","score":7,"severity":"HIGH"}],"references":["https://github.com/uutils/coreutils/issues/10020","http://www.openwall.com/lists/oss-security/2026/05/04/4","http://www.openwall.com/lists/oss-security/2026/05/04/5","http://www.openwall.com/lists/oss-security/2026/05/04/6"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35352","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Modified","weaknesses":["CWE-367"],"productCriteria":["cpe:2.3:a:uutils:coreutils:-:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:37.597","lastModified":"2026-10-26T21:10:00.170"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
