uutils coreutils doesn't preserve file ownership during moves across different filesystem boundaries

Published: 4/22/2026Modified: 6/2/2026

Also known as:GHSA-957r-r8gc-vv3hCGA-f3x5-p9x4-f5vf

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.
