In 1.5.0 and earlier, the permissions granted to the virt-handler service account, such as the ability to update VMI and patch nodes, could be abused to force a VMI migration to an attacker-controlled node. This vulnerability could otherwise allow an attacker to mark all nodes as unschedulable, potentially forcing the migration or creation of privileged pods onto a compromised node.","published":"2025-11-07T22:59:47.228Z","modified":"2026-08-12T03:51:48.053887249Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.7.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64436.json"},{"type":"ADVISORY","url":"https://github.com/kubevirt/kubevirt/security/advisories/GHSA-7xgm-5prm-v5gc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64436"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:48.053887249Z"}}
