CVE-2026-35381: Uutils Coreutils

Low severity, CVSS 3.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Uutils Coreutils: before 0.8.0 (fixed in 0.8.0)
