Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35364[0]:
| A Time-of-Check to Time-of-Use (TOCTOU) race condition exists in the
| mv utility of uutils coreutils during cross-device operations. The
| utility removes the destination path before recreating it through a
| copy operation. A local attacker with write access to the
| destination directory can exploit this window to replace the
| destination with a symbolic link. The subsequent privileged move
| operation will follow the symlink, allowing the attacker to redirect
| the write and overwrite an arbitrary target file with contents from
| the source.
