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-2011-2519 in the wild and no public exploit code.\n\nAffected product: Redhat Enterprise Linux Desktop. 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-2011-2519/ (Markdown: https://insights.sbomify.com/CVE-2011-2519/index.md)","id":"CVE-2011-2519","markdown":"https://insights.sbomify.com/CVE-2011-2519/index.md","name":"CVE-2011-2519","record":{"aliases":["GHSA-7vg8-g6px-4578"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Linux kernel Xen","requires_auth":"low_privilege","summary":"Guest users can crash the hypervisor via invalid pointer dereference when hardware assisted paging is disabled.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"xen","vendor":"xen"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:S/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"Xen in the Linux kernel, when running a guest on a host without hardware assisted paging (HAP), allows guest users to cause a denial of service (invalid pointer dereference and hypervisor crash) via the SAHF instruction.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Null dereference in n/a","id":"CVE-2011-2519","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"redhat:enterprise_linux_desktop","products":["redhat:enterprise_linux_desktop","redhat:enterprise_linux_server","redhat:enterprise_linux_workstation","xen:xen"],"type":"null_dereference","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Deserialization in n/a","id":"CVE-2011-2520"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2011-2518"},"products":["n/a"],"published":"2013-12-27","related":[{"cvss_score":9.8,"headline":"Information disclosure in n/a","id":"CVE-2016-5405","kev_date_added":null,"published":"2017-06-08"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-7050","kev_date_added":null,"published":"2017-06-08"},{"cvss_score":9.8,"headline":"Null dereference in n/a","id":"CVE-2014-8241","kev_date_added":null,"published":"2016-12-14"},{"cvss_score":9.4,"headline":"Denial of service in n/a","id":"CVE-2014-8567","kev_date_added":null,"published":"2014-11-14"},{"cvss_score":8.8,"headline":"Path traversal in yum-utils:","id":"CVE-2018-10897","kev_date_added":null,"published":"2018-08-01"},{"cvss_score":7.8,"headline":"Memory corruption in UnZip","id":"CVE-2014-8139","kev_date_added":null,"published":"2020-01-31"},{"cvss_score":7.8,"headline":"Memory corruption in UnZip","id":"CVE-2014-8140","kev_date_added":null,"published":"2020-01-31"}],"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":"Guest users can crash the hypervisor via invalid pointer dereference when hardware assisted paging is disabled.","url":"https://insights.sbomify.com/CVE-2011-2519/"}
