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-2015-8550 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-2015-8550/ (Markdown: https://insights.sbomify.com/CVE-2015-8550/index.md)","id":"CVE-2015-8550","markdown":"https://insights.sbomify.com/CVE-2015-8550/index.md","name":"CVE-2015-8550","record":{"aliases":["DEBIAN-CVE-2015-8550","GHSA-cv84-8x9g-5qcr","UBUNTU-CVE-2015-8550"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Xen hypervisor","requires_auth":"high_privilege","summary":"Local guest administrators can crash the host or gain privileges via a double fetch race condition in Xen PV backends.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"suse_linux_enterprise_real_time_extension","vendor":"novell"},{"product":"xen","vendor":"xen"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-284","name":"Improper Access Control"}],"description":"Xen, when used on a system providing PV backends, allows local guest OS administrators to cause a denial of service (host OS crash) or gain privileges by writing to memory shared between the frontend and backend, aka a double fetch vulnerability.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-07-15","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-15T17:06:00Z","kind":"github_poc","ref":"https://github.com/WhatsWrongAndWhy/CVE-2015-8550","stars":0,"title":null}],"tier":"poc_unverified"},"has_fix":true,"headline":"Race condition in n/a","id":"CVE-2015-8550","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"xen:xen","products":["xen:xen"],"type":"race_condition","year":"2015"},"n_packages":0,"n_references":11,"next":{"headline":"Null dereference in n/a","id":"CVE-2015-8551"},"packages":[],"prev":{"headline":"PyAMF vulnerable to XML external entity (XXE)","id":"CVE-2015-8549"},"products":["n/a"],"published":"2016-04-14","related":[{"cvss_score":4.9,"headline":"Denial of service in n/a","id":"CVE-2015-7833","kev_date_added":null,"published":"2015-10-19"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Local guest administrators can crash the host or gain privileges via a double fetch race condition in Xen PV backends.","url":"https://insights.sbomify.com/CVE-2015-8550/"}
