Remote code execution via integer overflow
Published Feb 13, 2024 · Updated Aug 10, 2026
Integer overflow in the WDAC OLE DB provider for SQL Server in Microsoft Windows allows remote attackers to execute code after user interaction. Microsoft identifies CWE-190 but has not disclosed the function, integer calculation, or untrusted input that overflows. User interaction is required, and successful exploitation permits arbitrary code execution on the affected system.
