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-2019-7309 in the wild and no public exploit code.\n\nAffected product: Gnu Glibc. 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-2019-7309/ (Markdown: https://insights.sbomify.com/CVE-2019-7309/index.md)","id":"CVE-2019-7309","markdown":"https://insights.sbomify.com/CVE-2019-7309/index.md","name":"CVE-2019-7309","record":{"aliases":["DEBIAN-CVE-2019-7309","GHSA-2g8x-3m62-h85f","UBUNTU-CVE-2019-7309"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["other"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU C Library","requires_auth":"low_privilege","summary":"A logic error in glibc's memcmp on x32 architecture may incorrectly report equal inputs, potentially affecting security checks relying on this function.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[],"description":"In the GNU C Library (aka glibc or libc6) through 2.29, the memcmp function for the x32 architecture can incorrectly return zero (indicating that the inputs are equal) because the RDX most significant bit is mishandled.","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":"Other in n/a","id":"CVE-2019-7309","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"other","year":"2019"},"n_packages":0,"n_references":4,"next":{"headline":"Integer overflow in n/a","id":"CVE-2019-7310"},"packages":[],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2019-7308"},"products":["n/a"],"published":"2019-02-03","related":[{"cvss_score":9.8,"headline":"scanf %mc off-by-one heap buffer overflow","id":"CVE-2026-5450","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-25139","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-1999-0199","kev_date_added":null,"published":"2020-10-06"},{"cvss_score":9.8,"headline":"Security feature bypass in glibc","id":"CVE-2019-1010022","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2005-3590","kev_date_added":null,"published":"2019-04-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18269","kev_date_added":null,"published":"2018-05-18"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-11236","kev_date_added":null,"published":"2018-05-18"}],"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":"2026-10-14","vendors":["n/a"]},"summary":"A logic error in glibc's memcmp on x32 architecture may incorrectly report equal inputs, potentially affecting security checks relying on this function.","url":"https://insights.sbomify.com/CVE-2019-7309/"}
