Kerentanan Unchecked Return Value pada redhat libnbd, redhat enterprise linux. Skor CVSS 3.1 4.8 (Medium) menurut NVD.

Deskripsi (NVD)

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.
