In uutils coreutils' chmod utility, recursive mode (-R) does not aggregate error statuses across multiple files. Instead, it returns the exit code of the last processed file only. Consequently, if errors such as 'Operation not permitted' occur on earlier files, these are not reflected in the final exit code, misleading automation or scripts that depend on accurate exit codes for error handling. This behavior affects versions prior to 0.6.0 and is classified under CWE-253 (Incorrect Check of Function Return Value).

Scripts or automated processes that rely on chmod's exit codes to verify successful permission changes may proceed under false assumptions of success. This can result in sensitive files retaining incorrect or overly restrictive permissions, potentially impacting system configuration or security posture. There is no direct confidentiality or availability impact reported, but the integrity of permission settings is affected.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should verify permissions manually after recursive chmod operations or avoid relying solely on exit codes for error detection until a fix is available.
