{"id":"AZL-105537","summary":"CVE-2026-102623 affecting package kubevirt 1.8.4-2","details":"A flaw was found in KubeVirt. An authenticated user with permission to create Virtual Machine Instances (VMIs) can cause a Denial of Service (DoS) by submitting a virtual machine definition with an empty ephemeral volume. The virt-controller component fails to properly validate the volume configuration, leading to an unhandled exception and application crash during processing. Because the malformed definition persists in the cluster, the controller enters a continuous crash loop, disrupting virtual machine lifecycle operations across the entire environment.","modified":"2026-10-05T05:34:30Z","published":"2026-09-29T17:17:06Z","upstream":["CVE-2026-102623"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-102623"}],"affected":[{"package":{"name":"kubevirt","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kubevirt"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"1.8.4-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105537.json"}}],"schema_version":"1.9.0"}
