Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35344[0]:
| The dd utility in uutils coreutils suppresses errors during file
| truncation operations by unconditionally calling Result::ok() on
| truncation attempts. While intended to mimic GNU behavior for
| special files like /dev/null, the uutils implementation also hides
| failures on regular files and directories caused by full disks or
| read-only file systems. This can lead to silent data corruption in
| backup or migration scripts, as the utility may report a successful
| operation even when the destination file contains old or garbage
| data.
