It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2025-64437 exists.\n\nAffected packages and fixed versions:\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3, 1.6.0-beta.0.0.20250801202148-3ce9f41c54d0\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3\n- kubevirt.io/kubevirt (Go): affected all versions; fixed in 1.5.3\n- kubevirt.io/kubevirt (Go): affected from 1.6.0-alpha.0; fixed in 1.6.1\n- kubevirt.io/kubevirt (Go): affected from 1.6.0-alpha.0; fixed in 1.6.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-64437/ (Markdown: https://insights.sbomify.com/CVE-2025-64437/index.md)","id":"CVE-2025-64437","markdown":"https://insights.sbomify.com/CVE-2025-64437/index.md","name":"CVE-2025-64437","record":{"aliases":["AZL-69805","AZL-69970","GHSA-2r4r-5x78-mvqf","GO-2025-4102","MINI-6wqx-5pj7-6hg8","MINI-hvp4-48v9-6fc5"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"upgrade","impacts":["data_modify","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Kubernetes VM add-on","requires_auth":"high_privilege","summary":"Attackers controlling the virt-launcher pod filesystem can change ownership of arbitrary host files via symlink exploitation, compromising host data integrity.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"kubevirt","vendor":"kubevirt"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"KubeVirt is a virtual machine management add-on for Kubernetes. In versions before 1.5.3 and 1.6.1, the virt-handler does not verify whether the launcher-sock is a symlink or a regular file. This oversight can be exploited, for example, to change the ownership of arbitrary files on the host node to the unprivileged user with UID 107 (the same user used by virt-launcher) thus, compromising the CIA (Confidentiality, Integrity and Availability) of data on the host. To successfully exploit this vulnerability, an attacker should be in control of the file system of the virt-launcher pod.
