{"id":"UBUNTU-CVE-2026-35381","details":"A logic error in the cut utility of uutils coreutils causes the utility to ignore the -s (only-delimited) flag when using the -z (null-terminated) and -d '' (empty delimiter) options together. The implementation incorrectly routes this specific combination through a specialized newline-delimiter code path that fails to check the record suppression status. Consequently, uutils cut emits the entire record plus a NUL byte instead of suppressing it. This divergence from GNU coreutils behavior creates a data integrity risk for automated pipelines that rely on cut -s to filter out undelimited data.","modified":"2026-05-14T12:21:51.713551100Z","published":"2026-04-22T17:16:00Z","upstream":["CVE-2026-35381"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-35381"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-35381"},{"type":"REPORT","url":"https://github.com/uutils/coreutils/pull/11394"}],"affected":[{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.20-1","0.0.22-1","0.0.23-1","0.0.23-2","0.0.23-3","0.0.24-1","0.0.24-2"],"ecosystem_specific":{"binaries":[{"binary_name":"rust-coreutils","binary_version":"0.0.24-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35381.json"}},{"package":{"name":"rust-coreutils","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/rust-coreutils?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0.30-1","0.0.30-2","0.0.30-2ubuntu2","0.1.0-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu1","0.1.0+git20250711.2ba3a33-0ubuntu2","0.1.0+git20250711.2ba3a33-0ubuntu3","0.1.0+git20250711.2ba3a33-0ubuntu4","0.1.0+git20250801.cf79675-0ubuntu1","0.1.0+git20250813.4af2a84-0ubuntu2","0.1.0+git20250813.4af2a84-0ubuntu4","0.1.0+git20250813.4af2a84-0ubuntu6","0.1.0+git20250813.4af2a84-0ubuntu7","0.2.2-0ubuntu1","0.2.2-0ubuntu2","0.2.2-0ubuntu2.1"],"ecosystem_specific":{"binaries":[{"binary_version":"0.2.2-0ubuntu2.1","binary_name":"rust-coreutils"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-35381.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:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
