A security flaw in the Slurm sbcast tool
(CVE-2026-65107) lets shared library files bypass security checks and
can crash nodes in your cluster.
What should I do?
Google updated the OS images that Cluster Toolkit supports
with the necessary patches for CVE-2026-65107. If a node hasn't been
recreated since September 7, 2026, then the node is vulnerable. To
update the node with the latest OS image, do one of the following:
Power down static nodes. Slurm recreates the node with
the patched OS image when you submit new jobs.
Reconfigure a running cluster. In the deployment
blueprint for your cluster, update the image family and redeploy the
cluster.
