Local information disclosure via untrusted pointer dereference
Published Jul 11, 2023 · Updated Feb 28, 2025
Untrusted pointer dereference in Microsoft Windows printer drivers allows local users to read sensitive information from system memory. Microsoft identifies the affected locus as the PostScript and PCL6 class printer drivers but has not published which pointer-handling operation accepts or dereferences untrusted data. Exploitation requires local low-privilege access, needs no user interaction, and affects confidentiality without reported data modification or service interruption.
