How to fix?

There is no fixed version for RHEL:8 container-tools:rhel8/buildah.

NVD Description

Note: Versions mentioned in the description apply only to the upstream container-tools:rhel8/buildah package and not the container-tools:rhel8/buildah package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

The source-address critical option in the Permissions returned by an authentication callback was only enforced for the PublicKeyCallback and VerifiedPublicKeyCallback paths, extending the fix for CVE-2026-46595. Permissions returned by the PasswordCallback, KeyboardInteractiveCallback, NoClientAuthCallback, and GSSAPIWithMICConfig.AllowLogin callbacks were not validated against the client's remote address, so a source-address restriction set by those callbacks was silently ignored. The check is now applied to the Permissions returned by any authentication callback.
