rust-coreutils: The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries
CVE-2026-35351 is fixed in rust-coreutils on 1 platform by DEBIAN-CVE-2026-35351 (version 0.9.0-1), released April 22, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
