Beschreibung
Component
dd
Description
If the output device is full, read-only, or otherwise unable to be truncated, dd reports success (exit 0) while leaving stale data in the output file.
Impact
Silent data corruption. Backup scripts relying on dd may believe a copy succeeded when it actually contains old/garbage data, leading to undetected data loss during recovery.
