Binding parameter number 32768 wraps that count to -32768. Binding parameter 32769 then writes about 2.5 MB of zeros starting 1.25 MB before the binding array, which crashes the application or leaves it running on a corrupted heap. Applications that build parameter lists from untrusted input, such as an IN (?, ?, ...) list, are exposed. Versions before psqlODBC 18.00.0005 are affected.","state":0,"publishedAt":"2026-10-12T17:42:59.581+00:00","modifiedAt":"2026-10-16T17:48:46.624+00:00","affected":[{"ecosystem":"Vendor product","name":"psqlODBC","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"PostgreSQL\",\n                    \"product\": \"psqlODBC\",\n                    \"repo\": \"https://github.com/postgresql-interfaces/psqlodbc\",\n                    \"programFiles\": [\n                        \"bind.c\"\n                    ],\n                    \"programRoutines\": [\n                        {\n                            \"name\": \"SQLBindParameter\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\",\n                    \"versions\": [\n                        {\n                            \"version\": \"08.01.0102\",\n                            \"lessThan\": \"18.00.0005\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"custom\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/postgresql-interfaces/psqlodbc/security/advisories/GHSA-cmfx-rm3r-p2jr"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109448","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109448","identifiers":["CVE-2026-109448"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
