{"id":"CVE-2026-35364","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-35364","summary":"uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition","details":"A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the mv utility of uutils coreutils during cross-device operations. The utility removes the destination path before recreating it through a copy operation. A local attacker with write access to the destination directory can exploit this window to replace the destination with a symbolic link. The subsequent privileged move operation will follow the symlink, allowing the attacker to redirect the write and overwrite an arbitrary target file with contents from the source.","published":"2026-04-22T18:31:45Z","modified":"2026-09-10T03:51:02.257714897Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":{"score":0.00091,"percentile":0.00565,"asOf":"2026-08-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"crates.io","name":"coreutils","fixedVersion":null}],"fix":null,"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35364"},{"type":"WEB","url":"https://github.com/uutils/coreutils/issues/10015"},{"type":"PACKAGE","url":"https://github.com/uutils/coreutils"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-10T03:51:02.257714897Z"}}
