Ubuntu 22.04.5 LTS
Description
We noticed that upon doing an upgrade to glibc to 2.35-0ubuntu3.11 on an Ubuntu 22.05.5 VM that it displayed issues with memory management. This resulted in an eventual OOM kill action by the kernel and mariadb was targeted (obv).
The memory usage pattern shows a significant change after restarting mariadb, which reloaded the updated library. This particular upgrade was the first one that included a patch for CVE-2025-8058 which indicates malloc as the target. https://ubuntu.com/security/CVE-2025-8058
The evidence for this being an issue with mariadb is anecdotal (hence suggestion of this being a potential issue) since we were not capturing process specific metrics. However, we figured it good enough that we should provide the information if others experience the same.
This issue is still present on the affected systems.
This server is part of a replicated cluster of 2 servers, the one here being the primary. As a result of the OOM kill, the second server was activated as primary write server and displays the same memory consumption pattern. We have this under observation right now.
We will provide updates as they become available.
