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-2012-5525 exists.\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-2012-5525/ (Markdown: https://insights.sbomify.com/CVE-2012-5525/index.md)","id":"CVE-2012-5525","markdown":"https://insights.sbomify.com/CVE-2012-5525/index.md","name":"CVE-2012-5525","record":{"aliases":["GHSA-wrrw-3jqq-qcvc"],"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":"high_privilege","summary":"Local PV guest administrators can crash the Xen hypervisor via a crafted GFN in the get_page_from_gfn hypercall, causing denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"xen","vendor":"xen"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"AV:L/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[],"description":"The get_page_from_gfn hypercall function in Xen 4.2 allows local PV guest OS administrators to cause a denial of service (crash) via a crafted GFN that triggers a buffer over-read.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":1,"nuclei":0,"refs":[{"date":null,"kind":"metasploit","ref":"post/linux/dos/xen_420_dos","stars":null,"title":"Linux DoS Xen 4.2.0 2012-5525"}],"tier":"weaponised"},"has_fix":true,"headline":"Denial of service in n/a","id":"CVE-2012-5525","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xen:xen","products":["xen:xen"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":7,"next":{"headline":"Other in n/a","id":"CVE-2012-5526"},"packages":[],"prev":{"headline":"Security feature bypass in n/a","id":"CVE-2012-5524"},"products":["n/a"],"published":"2012-12-13","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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"BSD-3-Clause","name":"Metasploit"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local PV guest administrators can crash the Xen hypervisor via a crafted GFN in the get_page_from_gfn hypercall, causing denial of service.","url":"https://insights.sbomify.com/CVE-2012-5525/"}
