An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-58147 in the wild and no public exploit code.\n\nAffected product: Xen Xen. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2025-58147/ (Markdown: https://insights.sbomify.com/CVE-2025-58147/index.md)","id":"CVE-2025-58147","markdown":"https://insights.sbomify.com/CVE-2025-58147/index.md","name":"CVE-2025-58147","record":{"aliases":["ALPINE-CVE-2025-58147","DEBIAN-CVE-2025-58147","GHSA-64c5-3xxf-ccjp","UBUNTU-CVE-2025-58147","openSUSE-SU-2025:15673-1"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"none","summary":"Out-of-bounds writes in Xen hypervisor Viridian hypercalls allow guest-to-host code execution or privilege escalation.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[{"product":"xen","vendor":"xen"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"[This CNA information record relates to multiple CVEs; the\ntext explains which aspects/vulnerabilities correspond to which CVE.]\n\nSome Viridian hypercalls can specify a mask of vCPU IDs as an input, in\none of three formats.
