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-2013-1920 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-2013-1920/ (Markdown: https://insights.sbomify.com/CVE-2013-1920/index.md)","id":"CVE-2013-1920","markdown":"https://insights.sbomify.com/CVE-2013-1920/index.md","name":"CVE-2013-1920","record":{"aliases":["GHSA-xgcf-925j-mrg9"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"Local guest kernels can exploit a use-after-free in Xen to inject events and gain privileges when XSM is enabled under memory pressure.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"xen","vendor":"xen"}],"cvss":{"score":4.4,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"Xen 4.2.x, 4.1.x, and earlier, when the hypervisor is running \"under memory pressure\" and the Xen Security Module (XSM) is enabled, uses the wrong ordering of operations when extending the per-domain event channel tracking table, which causes a use-after-free and allows local guest kernels to inject arbitrary events and gain privileges via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Use after free in n/a","id":"CVE-2013-1920","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xen:xen","products":["xen:xen"],"type":"use_after_free","year":"2013"},"n_packages":0,"n_references":13,"next":{"headline":"Information disclosure in n/a","id":"CVE-2013-1921"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2013-1919"},"products":["n/a"],"published":"2013-04-12","related":[{"cvss_score":10,"headline":"Privilege escalation in n/a","id":"CVE-2017-10912","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10918","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10920","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2017-10921","kev_date_added":null,"published":"2017-07-05"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-27466","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-58142","kev_date_added":null,"published":"2025-09-11"},{"cvss_score":9.8,"headline":"Mutiple vulnerabilities in the Viridian interface","id":"CVE-2025-58143","kev_date_added":null,"published":"2025-09-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local guest kernels can exploit a use-after-free in Xen to inject events and gain privileges when XSM is enabled under memory pressure.","url":"https://insights.sbomify.com/CVE-2013-1920/"}
