CVE-2026-120959 PUBLISHED

MongoDB Atlas SQL ODBC Driver uses ignored SQLBindCol BufferLength as fixed-width row-array stride, causing out-of-bounds writes

Assigner: mongodb
Reserved: 03.11.2026 Published: 03.11.2026 Updated: 03.11.2026

A memory-handling flaw in the MongoDB Atlas SQL ODBC Driver can cause values returned for a query to be written outside the bounds of a buffer provided by the calling application. A party able to influence the values a query returns may cause data to be placed at an unintended location in the client application's memory, which may result in unintended modification of that memory or termination of the client process. Reaching this condition depends on a specific, application-chosen way of requesting several result rows at once.
