Vulnerability description
DayBreach CVE AI Research
CVE-2026-35339 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
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.
