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-2010-0309 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-2010-0309/ (Markdown: https://insights.sbomify.com/CVE-2010-0309/index.md)","id":"CVE-2010-0309","markdown":"https://insights.sbomify.com/CVE-2010-0309/index.md","name":"CVE-2010-0309","record":{"aliases":["AZL-34841","AZL-6509","GHSA-wqgc-3hgm-hrw9"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"KVM virtualization","requires_auth":"low_privilege","summary":"Guest OS users can crash or hang the host OS by reading /dev/port due to improper PIT emulation handling in KVM.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"kernel","vendor":"linux"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-16","name":null}],"description":"The pit_ioport_read function in the Programmable Interval Timer (PIT) emulation in i8254.c in KVM 83 does not properly use the pit_state data structure, which allows guest OS users to cause a denial of service (host OS crash or hang) by attempting to read the /dev/port file.","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-2010-0309","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"denial_of_service","year":"2010"},"n_packages":0,"n_references":13,"next":{"headline":"Privilege escalation in n/a","id":"CVE-2010-0310"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2010-0308"},"products":["n/a"],"published":"2010-02-12","related":[{"cvss_score":7.8,"headline":"Null dereference in n/a","id":"CVE-2009-2844","kev_date_added":null,"published":"2009-08-18"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2009-1389","kev_date_added":null,"published":"2009-06-16"},{"cvss_score":7.2,"headline":"Null dereference in n/a","id":"CVE-2009-2767","kev_date_added":null,"published":"2009-08-14"},{"cvss_score":6.9,"headline":"Memory corruption in n/a","id":"CVE-2009-2406","kev_date_added":null,"published":"2009-07-31"},{"cvss_score":4.9,"headline":"Information disclosure in n/a","id":"CVE-2009-2847","kev_date_added":null,"published":"2009-08-18"},{"cvss_score":4.6,"headline":"Use after free in n/a","id":"CVE-2009-3624","kev_date_added":null,"published":"2009-11-02"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Guest OS users can crash or hang the host OS by reading /dev/port due to improper PIT emulation handling in KVM.","url":"https://insights.sbomify.com/CVE-2010-0309/"}
