There is no fixed version for Centos:10 osbuild-composer-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream osbuild-composer-core package and not the osbuild-composer-core package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

An unrecovered panic in the event stream header decoder in Amazon AWS SDK for Go v2 before release-2026-03-23 might allow an unauthenticated remote actor to terminate the consuming application process via a crafted event stream response frame containing a header value type outside the valid range.

To remediate this issue, users should upgrade to release-2026-03-23 or later, and patch any forked or derivative code.
