The are_files_identical function opens and reads from both input paths to compare content without first verifying if the paths refer to regular files. If an input path is a FIFO or a pipe, this pre-read operation drains the stream, leading to silent data loss before the actual comparison logic is executed. Additionally, the utility may hang indefinitely if it attempts to pre-read from infinite streams like /dev/zero.","state":0,"publishedAt":"2026-04-22T17:16:36.903+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:L/PR:L/UI:N/S:U/C:N/I:L/A:L","score":4.4,"severity":"MEDIUM"}],"references":["https://github.com/uutils/coreutils/pull/9545","https://github.com/uutils/coreutils/releases/tag/0.6.0"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-35347","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Analyzed","weaknesses":["CWE-20"],"productCriteria":["cpe:2.3:a:uutils:coreutils:*:*:*:*:*:rust:*:*"],"sourceDates":{"published":"2026-04-22T17:16:36.903","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.
