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-2010-4255 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2010-4255/ (Markdown: https://insights.sbomify.com/CVE-2010-4255/index.md)","id":"CVE-2010-4255","markdown":"https://insights.sbomify.com/CVE-2010-4255/index.md","name":"CVE-2010-4255","record":{"aliases":["DEBIAN-CVE-2010-4255","GHSA-3x4p-cw57-cgf8"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Xen hypervisor","requires_auth":"low_privilege","summary":"Guest OS users can cause a host OS denial of service via crafted memory access in Xen hypervisor when paravirtualization is enabled.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"xen","vendor":"citrix"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"AV:A/AC:L/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[],"description":"The fixup_page_fault function in arch/x86/traps.c in Xen 4.0.1 and earlier on 64-bit platforms, when paravirtualization is enabled, does not verify that kernel mode is used to call the handle_gdt_ldt_mapping_fault function, which allows guest OS users to cause a denial of service (host OS BUG_ON) via a crafted memory access.","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":"Denial of service in n/a","id":"CVE-2010-4255","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2010"},"n_packages":0,"n_references":9,"next":{"headline":"Denial of service in n/a","id":"CVE-2010-4256"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2010-4254"},"products":["n/a"],"published":"2011-01-25","related":[{"cvss_score":7.4,"headline":"Privilege escalation in n/a","id":"CVE-2011-1898","kev_date_added":null,"published":"2011-08-12"},{"cvss_score":7.2,"headline":"Missing authorization in n/a","id":"CVE-2008-5716","kev_date_added":null,"published":"2008-12-24"},{"cvss_score":7.2,"headline":"Missing authorization in n/a","id":"CVE-2008-4405","kev_date_added":null,"published":"2008-10-03"},{"cvss_score":6.9,"headline":"Integer overflow in n/a","id":"CVE-2011-1583","kev_date_added":null,"published":"2011-08-12"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2010-4238","kev_date_added":null,"published":"2011-01-22"},{"cvss_score":5.5,"headline":"Denial of service in n/a","id":"CVE-2010-4247","kev_date_added":null,"published":"2011-01-11"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Guest OS users can cause a host OS denial of service via crafted memory access in Xen hypervisor when paravirtualization is enabled.","url":"https://insights.sbomify.com/CVE-2010-4255/"}
