CVE-2024-28926Network attack vector

Remote code execution via heap buffer overflow

Published Apr 9, 2024 · Updated May 3, 2025

Heap-based buffer overflow in Microsoft OLE DB Driver 18 before 18.7.0002.0 and Driver 19 before 19.3.0003.0 allows remote attackers to execute code. The driver mishandles attacker-controlled data in a heap buffer, but Microsoft has not disclosed the affected function or exact length-check failure. Exploitation requires user interaction that causes the driver to process attacker-controlled network data, with code running in the client process context.
