Affected: >= 10.6.1 and < 10.6.26 · >= 10.11.1 and < 10.11.17 · >= 11.4.1 and < 11.4.11 · >= 11.8.1 and < 11.8.7 · 12.3.1

Fixed in: 10.6.26, 10.11.17, 11.4.11, 11.8.7

Safe to downgrade to: a release before 10.6.1

1. Check installed version

apt-cache policy mariadb || rpm -q mariadb || mariadb --version

2. UPGRADE to 10.6.26 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mariadb

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 10.6.1 (Debian / Ubuntu)

apt-cache madison mariadb sudo apt install mariadb=<VERSION_BEFORE_10.6.1> sudo apt-mark hold mariadb

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

dnf --showduplicates list mariadb sudo dnf downgrade mariadb-<VERSION_BEFORE_10.6.1> sudo dnf versionlock add mariadb

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.
