2. UPGRADE to 24.1.6 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade drivelock

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 24.1 (Debian / Ubuntu)

apt-cache madison drivelock sudo apt install drivelock=<VERSION_BEFORE_24.1> sudo apt-mark hold drivelock

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

dnf --showduplicates list drivelock sudo dnf downgrade drivelock-<VERSION_BEFORE_24.1> sudo dnf versionlock add drivelock

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.
