{"id":"CVE-2026-35353","summary":"uutils coreutils mkdir Permission Exposure Race Condition with -m","details":"The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions (typically 0755) before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces a brief window where a directory intended to be private is accessible to other users, potentially leading to unauthorized data access.","aliases":["GHSA-mj6p-44ch-cq69"],"modified":"2026-07-08T08:05:07.239301339Z","published":"2026-04-22T16:08:09.923Z","database_specific":{"cwe_ids":["CWE-367"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35353.json","cna_assigner":"canonical"},"references":[{"type":"WEB","url":"https://github.com/uutils"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35353.json"},{"type":"ADVISORY","url":"https://github.com/uutils/coreutils/releases/tag/0.6.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35353"},{"type":"FIX","url":"https://github.com/uutils/coreutils/pull/10036"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/uutils/coreutils","events":[{"introduced":"0"},{"fixed":"2319a99057d11b0c9744c885df84806eea019166"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"0.6.0"}],"cpe":"cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*"}}],"versions":["latest-commit","0.5.0","0.4.0","0.3.0","0.2.2","0.2.0","0.1.0","0.0.30-delete","0.0.30","0.0.29","0.0.28","0.0.27","0.0.26","0.0.25","0.0.24","0.0.23","0.0.22","0.0.21","0.0.20","0.0.19","0.0.18","0.0.17","0.0.16","0.0.15","0.0.14","0.0.13","0.0.12","0.0.9","0.0.8","0.0.7","0.0.6","0.0.5","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35353.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
