Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2025-14911 in the wild and no public exploit code.\n\nAffected product: MongoDB Mongo-c-driver. 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-2025-14911/ (Markdown: https://insights.sbomify.com/CVE-2025-14911/index.md)","id":"CVE-2025-14911","markdown":"https://insights.sbomify.com/CVE-2025-14911/index.md","name":"CVE-2025-14911","record":{"aliases":["DEBIAN-CVE-2025-14911","GHSA-pc4j-j33v-hr73"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"MongoDB C driver","requires_auth":"low_privilege","summary":"An integer overflow in the MongoDB C driver allows attackers to cause heap allocation failures via malformed GridFS metadata, leading to denial of service.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mongodb","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-120","name":"Buffer Copy without Checking Size of Input"}],"description":"User-controlled chunkSize metadata from MongoDB lacks appropriate validation allowing malformed GridFS metadata to overflow the bounding container.","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":"Integer Overflow in GridFS chunkSize Leading to Heap Allocation Failure","id":"CVE-2025-14911","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"integer_overflow","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"IBM InfoSphere Information Server is vulnerable to server-side request forgery","id":"CVE-2025-14912"},"packages":[],"prev":{"headline":"Edimax BR-6208AC FTP Daemon Service handle_retr path traversal","id":"CVE-2025-14910"},"products":["Mongo-c-driver"],"published":"2026-01-27","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["MongoDB"]},"summary":"An integer overflow in the MongoDB C driver allows attackers to cause heap allocation failures via malformed GridFS metadata, leading to denial of service.","url":"https://insights.sbomify.com/CVE-2025-14911/"}
