Safe to downgrade to: no unaffected older release

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update

If no patch exists yet

OS downgrades are not safe. Apply the vendor mitigation from the advisory and restrict exposure.

netapp hci baseboard management controller DOWNGRADE

Affected: h300s · h410c · h410s · h500s · h700s

Fixed in: no fixed release known

Safe to downgrade to: a release before h300s

1. Check installed version

apt-cache policy hci-baseboard-management-controller || rpm -q hci-baseboard-management-controller || hci-baseboard-management-controller --version

2. No fixed release: DOWNGRADE to a release before h300s (Debian / Ubuntu)

apt-cache madison hci-baseboard-management-controller sudo apt install hci-baseboard-management-controller=<VERSION_BEFORE_h300s> sudo apt-mark hold hci-baseboard-management-controller

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list hci-baseboard-management-controller sudo dnf downgrade hci-baseboard-management-controller-<VERSION_BEFORE_h300s> sudo dnf versionlock add hci-baseboard-management-controller

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.
