Local information disclosure via out-of-bounds read
Published Sep 8, 2026 · Updated Sep 9, 2026
Out-of-bounds read in Microsoft Windows Print Spooler Components allows local users to read memory on affected Windows 10, 11, and Server systems. Microsoft has not disclosed the specific function, buffer, or input that causes the component to read beyond its intended bounds. Low-privileged local access is required; the reported consequence is memory disclosure without data modification or service interruption.
