Identified - Due to the recently disclosed “[Copy Fail](https://copy.fail/)” (CVE-2026-31431) Linux kernel vulnerability, our system administrators are actively applying mitigation measures and updates across all Tartu University HPC Center systems today. As a result, you may experience temporary interruptions or reduced service availability while this work is in progress. All UT HPC services are affected. At this time, the work is expected to be completed today; however, we will provide further updates if the situation extends beyond today.continuing to work on a fix for this incident. **Users running their own Linux virtual machines are advised to apply the recommended patches on their systems by following the instructions provided in the “Mitigation” section of the** [**CVE-2026-31431 advisory**](https://copy.fail/)**.** Thank you for your understanding..

Apr 30, 08:41:41 GMT+0
Identified - We are providing an update on the mitigation for the Critical Linux Kernel Vulnerability (CVE-2026-31431). We have learned that the mitigation described in CVE-2026-31431 is not effective on all Linux-based instances. Specifically, machines running RHEL or SUSE operating systems are currently not supported. As the respective OS providers have not yet released the required patches, we are recommending the following steps: ``` python3 -c " import socket, sys try: &nbsp; &nbsp;s = socket.socket(socket.AF_ALG, socket.SOCK_SEQPACKET, 0) &nbsp; &nbsp;s.bind(('aead', 'authencesn(hmac(sha256),cbc(aes))')) &nbsp; &nbsp;print('VULNERABLE - &nbsp;continue with next steps') &nbsp; &nbsp;sys.exit(1) except OSError as e: &nbsp; &nbsp;print('Not vulnerable:', e) &nbsp; &nbsp;sys.exit(0) " ``` 2\. Add a kernel parameter of `initcall_blacklist=algif_aead_init` to `/etc/default/grub`: ``` sed -i "s|^\(GRUB_CMDLINE_LINUX=\".*\)\"\s*$|\1 initcall_blacklist=algif_aead_init\"|" /etc/default/grub ``` 3\. Check the result: ``` grep GRUB_CMDLINE_LINUX /etc/default/grub # The line needs to end with initcall_blacklist=algif_aead_init", for example GRUB_CMDLINE_LINUX="... initcall_blacklist=algif_aead_init" Fix manually if necessary ``` 4\. Update GRUB configuration: ``` grub2-mkconfig -o /boot/grub2/grub.cfg ``` 5\. Reboot the machine: ``` reboot -h now ``` 6\. Check again with the first script For instance, running Debian or Ubuntu, mitigation can be applied by installing the latest available kernel version and rebooting the machine. .

Identified - Ajavahemikus 22 kuni 24 august on meil kavas UT HPC riistvaral asuva kohaliku Galaxy tarkvara versiooni uuendus, et saaksite osa lisandunud platvormi kasutajamugavuse funktsioonidest. Kuna sisuliselt on tegemist terve süsteemi värskendusega, siis mõjutab see nii sisselogimist kui ka sel perioodil aktiivselt jooksvaid töid. Tööde käivitamise paneme lukku juba eelneval päeval (21\. augustil), kuid tulemusi sirvida, töövooge koostada või mugandada jms. toiminguid saate teha kuni reede 22\. augusti hommikuni. Uuendatud serverisse saate taas sisse logida ja töid käivitada 24\. augustil. Vabandame võimalike ebamugavuste pärast. Kui teil on kõnealusel nädala plaanis jooksutada ressursimahukaid ja pikki analüüse ning kahtlete, kas ja kuidas neid täies mahus serveri aktiivsesse ajaaknasse mahutada, siis võtke meiega julgesti ühendust kirjutades aadressil [support@hpc.ut.ee](mailto:support@hpc.ut.ee) või otse vestluskanalite kaudu. \---------------------------------------------- Between August 22nd and 24th, we plan to upgrade the version of the local Galaxy server running on UT HPC hardware to enable new user convenience features of the platform. Since it is essentially an system update, it will affect both login and actively running jobs during this period. We will lock the launch of jobs the day before (August 21st), but you can perform tasks such as browsing results, creating or customizing workflows, etc. until the morning of Friday, August 22st. We apologise for any inconvenience this may cause. If you have resource-intensive and long-running analyses planned for this week and are unsure whether and how to fit them into the server's active time window, please feel free to contact us via [support@hpc.ut.ee](mailto:support@hpc.ut.ee) or direct messages..

Identified - HPC cluster Rocket updates are scheduled for July 2025 that will improve the cluster's performance and capabilities. **1) Login Node Updates** We'll be performing system updates on both login nodes this month: * **Login1**: July 15th * **Login2**: July 22nd To minimize disruption, we'll close new SSH connections one week before each update, allowing existing connections to naturally expire. One of the login nodes will remain available at all times, so you won't experience any service downtime. **2) Slurm Update** On **July 22nd, starting at 15:00**, we'll be upgrading Slurm from version 23.02 to 23.11\. Your running jobs won't be affected, and you'll be able to submit new jobs during the update. However, commands like sacct, sacctmgr, and related tools will be unavailable during the update. The process should take about two hours but may run longer. We After July 22nd, the compute nodes will be updated in a rolling fashion. This means some nodes will be temporarily drained until all updates are complete, which may result in longer queue times depending on cluster usage..

We have been informed that Estonian residents will probably not notice the frequency band change. However, during this switchover, Estonia’s electricity supply will be more vulnerable than usual, and technical failures can never be completely ruled out. If necessary, the University of Tartu HPC Center is prepared for potential electrical blackouts by activating our generator and UPS. Depending on the duration of the outage, we may need to shut down some non-critical services to optimize energy consumption. The HPC cluster's compute nodes would be the first units to shut down. We will update you about the changes in our service here on the status page. Stay safe, UT HPC Center.

Identified - The Kubernetes cluster hosting impacted services currently has issues due to two outstanding bugs, one in the Linux kernel and one in Longhorn. We will upgrade both of these today evening on all nodes, to prevent future issues. The plan is to not impact workload availability, but as this is a big upgrade, no promises can be made..
