CVE-2026-35351 Details
Description
The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and migrations, causing files moved by a privileged user (e.g., root) to become root-owned unexpectedly, which can lead to information disclosure or restricted access for the intended owners.
A vulnerability exists in the mv utility of uutils coreutils, where file ownership is not preserved during moves across different filesystem boundaries. Instead of maintaining the source metadata, the utility reverts to a copy-and-delete method that assigns the destination file to the caller's UID/GID. This issue disrupts backups and file migrations, causing files moved by privileged users, such as root, to be incorrectly owned by root. Such ownership changes can lead to unauthorized access or information disclosure for the intended file owners.
Users can update to the latest version of uutils coreutils, where this issue has been addressed. Instructions for downloading the updated version are available on the uutils coreutils GitHub page.
