AI-suggested

Until a fix is available, users should be aware of this behavior and consider additional verification steps after using dd to ensure truncation succeeded, especially in critical backup or migration workflows. Monitoring return values explicitly or using alternative tools that properly report truncation errors may mitigate risk.

Description

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.
