Detailsinfo

A vulnerability, which was classified as problematic, was found in Uutils coreutils up to 0.5.x. Affected is some unknown functionality of the component ChownExecutor. The manipulation with an unknown input leads to a function return value vulnerability. CWE is classifying the issue as CWE-253. The product incorrectly checks a return value from a function, which prevents it from detecting errors or exceptional conditions. This is going to have an impact on integrity. CVE summarizes:

A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations. The final exit code is determined only by the last file processed. If the last operation succeeds, the command returns 0 even if earlier ownership or group changes failed due to permission errors. This can lead to security misconfigurations where administrative scripts incorrectly assume that ownership has been successfully transferred across a directory tree.

The weakness was shared by Zellic. The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-35340 since 04/02/2026. The exploitability is told to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available.
