{"id":"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.","aliases":["GHSA-46xp-26xh-hpqh","GO-2025-4110"],"modified":"2026-04-14T05:03:17.355102Z","published":"2025-11-18T22:10:19.661Z","related":["CGA-g7pw-q6w8-cpxr","SUSE-SU-2025:4330-1","SUSE-SU-2026:20551-1","SUSE-SU-2026:20610-1","openSUSE-SU-2026:20281-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64324.json","cwe_ids":["CWE-200","CWE-732"],"cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kubevirt/kubevirt","events":[{"introduced":"d347811ba84f31aaea00b6e36dcf1ddaa6687034"},{"fixed":"cd2805cb993960b24634a021dca991814801808d"}]}],"versions":["v1.7.0-alpha.0","v1.7.0-beta.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-64324.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N"}]}
