An actor who can influence the size of documents serialized by an embedding application can corrupt adjacent process memory or terminate the process. Reaching this issue requires the application to use the BSON bulk-writer API and produce a precise cumulative document size.","state":0,"publishedAt":"2026-10-08T18:40:32.206+00:00","modifiedAt":"2026-10-08T19:19:51.552+00:00","affected":[{"ecosystem":"Vendor product","name":"C Driver","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"MongoDB\",\n                    \"product\": \"C Driver\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0.5.0\",\n                            \"lessThan\": \"1.30.13\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"2.0.0\",\n                            \"lessThan\": \"2.5.6\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N","score":5.9,"severity":"MEDIUM"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","score":5.7,"severity":"MEDIUM"}],"references":["https://jira.mongodb.org/browse/CDRIVER-6418"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-106431","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-106431","identifiers":["CVE-2026-106431"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
