CVE-2022-0485

MEDIUM

libnbd - Unchecked Return Value in nbdcopy Multi-threaded Copy Operation

Title source: llm
STIX 2.1

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.
