Last modified Jun 17, 2026

CVE-2022-0485 is a medium-severity vulnerability rated 4.8/10 on the CVSS scale. A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. EPSS estimates a 0.76% chance of exploitation in the next 30 days.

Description

A flaw was found in the copying tool `nbdcopy` of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the *error parameter. This could result in the silent creation of a corrupted destination image.
