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-2026-62437 in the wild and no public exploit code.\n\nAffected product: 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-2026-62437/ (Markdown: https://insights.sbomify.com/CVE-2026-62437/index.md)","id":"CVE-2026-62437","markdown":"https://insights.sbomify.com/CVE-2026-62437/index.md","name":"CVE-2026-62437","record":{"aliases":["ALPINE-CVE-2026-62437","DEBIAN-CVE-2026-62437","GHSA-vfxv-3qcw-g966","UBUNTU-CVE-2026-62437"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"A race condition in Xen allows a guest to cause a memory leak by re-binding IRQs during termination, potentially leading to denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"XEN","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"When guests are terminated, various pieces of cleanup need carrying out.\nThe cleaning up of PCI devices which were assigned to guests, and the\nassociated removal of tracking structures for IRQs used by the devices\noccurs relatively early in the process.
