The program attempts to prevent data loss by checking for identity between input and output files using their file paths before initiating the split operation. However, the utility subsequently opens the output file with truncation after this path-based validation is complete. A local attacker with write access to the directory can exploit this race window by manipulating mutable path components (e.g., swapping a path with a symbolic link). This can cause split to truncate and write to an unintended target file, potentially including the input file itself or other sensitive files accessible to the process, leading to permanent data loss.","state":0,"publishedAt":"2026-04-22T17:16:42.127+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:N/I:H/A:H","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/uutils/coreutils/pull/11401"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35374","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-367"],"productCriteria":["cpe:2.3:a:uutils:coreutils:-:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:42.127","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.
