Note

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

3. If no update is available yet, DOWNGRADE to a release before 11.6.401 (Debian / Ubuntu)

apt-cache madison data-loss-prevention sudo apt install data-loss-prevention=<VERSION_BEFORE_11.6.401> sudo apt-mark hold data-loss-prevention

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list data-loss-prevention sudo dnf downgrade data-loss-prevention-<VERSION_BEFORE_11.6.401> sudo dnf versionlock add data-loss-prevention

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.
