Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

dnf --showduplicates list wazuh sudo dnf downgrade wazuh-<VERSION_BEFORE_4.6.0> sudo dnf versionlock add wazuh

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
