CVE-2026-35339

uutils coreutils chmod False Success Exit Code in Recursive Mode

Published: Apr 22, 2026Updated: Apr 22, 2026 Sources: CVE List NVD
NVD MITRE
5.5CVSS
MEDIUM

The recursive mode (-R) of the chmod utility in uutils coreutils incorrectly handles exit codes when processing multiple files. The final return value is determined solely by the success or failure of the last file processed. This allows the command to return an exit code of 0 (success) even if errors were encountered on previous files, such as 'Operation not permitted'. Scripts relying on these exit codes may proceed under a false sense of success while sensitive files remain with restrictive or incorrect permissions.
