Improper Handling of Exit Codes in uutils coreutils Chmod Utility

CVE-2026-35339

What is CVE-2026-35339?

The chmod utility in uutils coreutils can mismanage exit codes during its recursive operation. Specifically, when applying permissions to multiple files, it only reports the success or failure of the last file. As a result, errors encountered on prior files can go undetected, leading to unintended file permission settings. This may permit scripts to believe that all operations were successful, potentially leaving sensitive files with incorrect permissions and thus posing a security risk.
