{"id":"CVE-2025-64324","aliases":["GHSA-46xp-26xh-hpqh","GO-2025-4110"],"url":"https://o3.security/vulnerability/CVE-2025-64324","summary":"KubeVirt Vulnerable to Arbitrary Host File Read and Write","details":"KubeVirt is a virtual machine management add-on for Kubernetes. The `hostDisk` feature in KubeVirt allows mounting a host file or directory owned by the user with UID 107 into a VM. However, prior to version 1.6.1 and 1.7.0, the implementation of this feature and more specifically the `DiskOrCreate` option (which creates a file if it doesn't exist) has a logic bug that allows an attacker to read and write arbitrary files owned by more privileged users on the host system. Versions 1.6.1 and 1.7.0 fix the issue.","published":"2025-11-18T22:10:19.661Z","modified":"2026-07-31T18:30:49.146518657Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.6.1"},{"ecosystem":"Go","name":"kubevirt.io/kubevirt","fixedVersion":"1.7.0-rc.0"}],"fix":{"url":"https://github.com/kubevirt/kubevirt/commit/00d03e43e3bf03e563136695a4732b65ed42d764","label":"kubevirt/kubevirt@00d03e4"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64324.json"},{"type":"ADVISORY","url":"https://github.com/kubevirt/kubevirt/security/advisories/GHSA-46xp-26xh-hpqh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64324"},{"type":"FIX","url":"https://github.com/kubevirt/kubevirt/commit/00d03e43e3bf03e563136695a4732b65ed42d764"},{"type":"FIX","url":"https://github.com/kubevirt/kubevirt/commit/ff3b69b08b6b9c8d08d23735ca8d82455f790a69"},{"type":"FIX","url":"https://github.com/kubevirt/kubevirt/pull/15037"},{"type":"PACKAGE","url":"https://github.com/kubevirt/kubevirt"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:30:49.146518657Z"}}
