It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-42327 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2022-42327/ (Markdown: https://insights.sbomify.com/CVE-2022-42327/index.md)","id":"CVE-2022-42327","markdown":"https://insights.sbomify.com/CVE-2022-42327/index.md","name":"CVE-2022-42327","record":{"aliases":["ALPINE-CVE-2022-42327","DEBIAN-CVE-2022-42327","GHSA-rgfj-62rr-5vf5","UBUNTU-CVE-2022-42327"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","data_read"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"A guest VM can bypass isolation to access shared xAPIC memory on Intel systems, potentially leading to privilege escalation or data leakage.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"xen","vendor":"xen"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"x86: unintended memory sharing between guests On Intel systems that support the \"virtualize APIC accesses\" feature, a guest can read and write the global shared xAPIC page by moving the local APIC out of xAPIC mode.
