CVE-2022-0485

Severity: medium (CVSS 4.8 v3.1)
Exploited in the wild: not listed in CISA KEV
EPSS: 1.0% probability of exploitation in the next 30 days
Public exploit or detection template: yes
Published: 2022-08-29 · updated 2026-06-17
Weakness: CWE-252

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.

Affected products

Red Hat Enterprise Linux: 8.0
[UNKNOWN] libnbd: before 1.11.8 — fixed in 1.11.8

How to fix

Upgrade to a fixed version: [UNKNOWN] libnbd 1.11.8. Check the vendor advisory for mitigations.
