University of Tartu cloud service emergency maintenance - mitigating a Linux kernel CVE
  • Resolved
    UTC
    Resolved

    The maintenance is finished. The UT Cloud service is available, and affected virtual machines and websites are restored.

  • Investigating
    UTC
    Investigating

    Due to a recently disclosed critical security vulnerability affecting Linux kernel-based virtualization platforms, we are implementing preventive security measures.

    As part of these maintenance activities, UT Cloud virtual machines (VMs) will be restarted. The VMs will be brought back online in a rolling manner over the next couple of hours. Besides virtual machines, some websites are also affected. In case of questions, please contact us at support@hpc.ut.ee.

    We apologize for any inconvenience and appreciate your understanding as we work to ensure the security and stability of our platform.

HPC cluster Rocket is temporarily unavailable due to ongoing security fixes (CVE-2026-46242 and CVE-2026-43499)
  • Resolved
    UTC
    Resolved

    HPC services are restored. Access to the UT Rocket cluster and Galaxy, Open OnDemand, and their services RStudio and Jupyter have been fully restored.

    The previously identified Linux kernel vulnerabilities have been addressed, and users can once again access the Rocket login nodes as usual and submit new jobs to the compute nodes.

  • Update
    UTC
    Update

    We are closing login nodes access again. The Rocket cluster is continuously not available. We expect the cluster to remain unavailable for most of the day. We apologize for the inconvenience and will provide updates as they become available.

    Due to the same security vulnerability, all SAPU machines are currently unavailable while security patches are being applied. We expect service to be restored later tonight. Thank you for your patience.

  • Monitoring
    UTC
    Monitoring

    We have applied the security patches to mitigate the vulnerability. The login nodes are now accessible; however, job submission remains disabled while we complete additional validation and testing. We require more time to ensure the cluster is fully stable before restoring normal operation.

    We appreciate your patience.

  • Investigating
    UTC
    Investigating

    Due to recently identified Linux kernel vulnerabilities (CVE-2026-46242 and CVE-2026-43499), we have temporarily disabled access to the UT HPC Rocket cluster as a precautionary measure to mitigate potential security risks.

    Currently, access to login nodes is unavailable. Also, new job submissions are temporarily disabled.

    Jobs that were already running before the access restrictions were applied continue to run and are not affected.

    Our system administrators are working to restore full service as quickly as possible. 

    Thank you for your patience!

Mainenance on all SAPU machines due to Linux kernel security vulnerabilities - service inaccessible
  • Identified

    Identified

    Due to the Linux kernel security vulnerabilities that also affected the HPC Rocket cluster (incident on 9 July 2026), all SAPU virtual machines are temporarily unavailable while security updates are being applied.

    We will provide updates as progress is made. Thank you for understanding.

    Maintenance of the University of Tartu HPC Center's cloud service will take place from 26 June to 3 July 2026.

    Error-prone operations will be performed outside business hours to minimize impact on users. In the minu.etais.ee self-service environment, there may be short-term interruptions in the UT HPC (Public) and UT HPC (Campus) cloud access or in virtual machines' network connection.

    Regular service updates are essential to maintaining a secure and resilient infrastructure while ensuring the long-term reliability of the services.

    If you have any questions or encounter any issues, please contact the technical support team at support@hpc.ut.ee.
