{"id":"GHSA-9gh9-hwpr-rvqq","summary":"uutils coreutils has a Time-of-Check to Time-of-Use (TOCTOU) race condition","details":"A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mkfifo utility of uutils coreutils. 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.","aliases":["CVE-2026-35352"],"modified":"2026-09-10T03:51:01.432445139Z","published":"2026-04-22T18:31:45Z","database_specific":{"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-04-30T17:09:11Z","nvd_published_at":"2026-04-22T17:16:37Z","cwe_ids":["CWE-367"]},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35352"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/10020"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/04/4"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/04/5"},{"type":"WEB","url":"http://www.openwall.com/lists/oss-security/2026/05/04/6"}],"affected":[{"package":{"name":"coreutils","ecosystem":"crates.io","purl":"pkg:cargo/coreutils"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"last_affected":"0.8.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-9gh9-hwpr-rvqq/GHSA-9gh9-hwpr-rvqq.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
