CVE-2026-102623 is a vulnerability in Red Hat OpenShift Virtualization 4's KubeVirt component where an authenticated user with permission to create Virtual Machine Instances can cause a denial of service. This occurs by submitting a virtual machine definition containing an empty ephemeral volume, which leads the virt-controller to crash due to improper validation. The crash causes the controller to enter a continuous crash loop, disrupting virtual machine lifecycle operations cluster-wide.
