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":"2026-04-22T16:08:07.422+00:00","modifiedAt":"2026-05-04T17:32:54.701+00:00","affected":[{"ecosystem":"https://github.com/uutils","name":"coreutils","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Uutils\",\n                    \"product\": \"coreutils\",\n                    \"platforms\": [\n                        \"Linux\",\n                        \"Unix\",\n                        \"macOS\"\n                    ],\n                    \"collectionURL\": \"https://github.com/uutils\",\n                    \"packageName\": \"coreutils\",\n                    \"repo\": \"https://github.com/uutils/coreutils\",\n                    \"defaultStatus\": \"affected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-35352","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-35352","identifiers":["CVE-2026-35352"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
