[Bruce Dubbs]

New point version.

[Douglas R. Reno]

We should stay on 11.8.x to keep on LTS

"Release date: 28 May 2026

MariaDB 12.3 is a long term release, maintained until June 2029. It is an evolution of MariaDB 12.2 with several entirely new features.

MariaDB 12.3.2 is a Stable (GA) release."

[Douglas R. Reno]

Sorry about that, I jumped the gun a bit on that and hadn't researched it yet. That is nice to see, hopefully it includes the OpenSSL fixes. Note that all users who upgrade will need to also upgrade their databases since it is a new major

[Bruce Dubbs]

Resetting to version 12.3.2. The openssl4 patch is still needed but is unchanged.

Hmm.

Upgrading MariaDB from version 11 to 12 requires a full backup, a clean shutdown, uninstalling the old binaries, installing the version 12 binaries, and running the mariadb-upgrade utility to update system tables. Skipping this backup can result in unrecoverable data.

We have instructions in the book to cover this already, but it's definitely not ideal. It should be under the instructions for installing the systemd units, but we should probably change the location on the page...

While going through a bit of research for this, I discovered that 11.8.8 contains fixes for three CVEs, one of which is rated as Critical:

• CVE-2026-49261 (10.0 Critical)
• CVE-2026-48165 (8.0 High)
• CVE-2026-48163 (8.0 High)

12.x is not affected as it removes the entirety of Galera from MariaDB. However, for existing users, upgrading this package could prove to be problematic if they are using the Galera functionality, and for 12.4/13.0 users I'm going to suggest upgrading to 11.8.8 in a security advisory as a result.
