Unauthenticated information disclosure via out-of-bounds read
Published Oct 13, 2026 · Updated Oct 13, 2026
Out-of-bounds read in Microsoft Windows GDI allows remote attackers to disclose information through network-delivered input. The CNA record identifies GDI as the affected component but does not disclose the input format, vulnerable routine, or failed bounds check. Exploitation requires user interaction and no authentication; the reported consequence is information disclosure, with no stated ability to modify data or interrupt service.
