Local information disclosure via buffer over-read
Published Jul 14, 2026 · Updated Jul 14, 2026
Buffer over-read in Microsoft Windows Print Spooler Components allows local users to disclose sensitive information from affected systems. Microsoft has not disclosed the affected routine, input, or operation that reads beyond the allocated buffer. Exploitation requires local low-privilege access and no user interaction, and the disclosed memory can contain data outside the intended buffer.
