Prior to 1.7.0-beta.0, a logic flaw in the virt-controller allows an attacker to disrupt the control over a running VMI by creating a pod with the same labels as the legitimate virt-launcher pod associated with the VMI. This can mislead the virt-controller into associating the fake pod with the VMI, resulting in incorrect status updates and potentially causing a DoS (Denial-of-Service). This vulnerability is fixed in 1.7.0-beta.0.","published":"2025-11-07T22:57:02.600Z","modified":"2026-08-12T03:51:24.896166249Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H"},"epss":{"score":0.00384,"percentile":0.3217,"asOf":"2026-09-17"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.7.0-beta.0"}],"fix":{"url":"https://github.com/kubevirt/kubevirt/commit/9a6f4a3a707992038ef705da4cb3bba8c89d36ba","label":"kubevirt/kubevirt@9a6f4a3"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64435.json"},{"type":"ADVISORY","url":"https://github.com/kubevirt/kubevirt/security/advisories/GHSA-9m94-w2vq-hcf9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64435"},{"type":"FIX","url":"https://github.com/kubevirt/kubevirt/commit/9a6f4a3a707992038ef705da4cb3bba8c89d36ba"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:24.896166249Z"}}
