CVE-2022-0485

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.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Use of nbdcopy --synchronous will avoid undetected data corruption, but comes at a potential performance cost by avoiding the speed benefits of asynchronous operations. See the upstream security advisory for more information.
