Due to another severe privilege escalation vulnerability in the Linux kernel, parts of the high-performance cluster are unavailable.

We are shutting down all machines running AlmaLinux 9. As a result, many CPU nodes and all GPU nodes will be temporarily unavailable.

As soon as a patch is available and has been applied, we will restore service.

Update as of July 09, 2026: Another security vulnerability now also affects the remaining AlmaLinux 8 machines. A kernel update is already available for testing and will be deployed shortly.
