Local kernel-memory disclosure via sensitive error messages
Published Sep 9, 2025 · Updated Sep 9, 2025
Information disclosure in the Microsoft Windows Kernel allows local users with low privileges to read sensitive kernel memory. Microsoft states only that the kernel generates an error message containing sensitive information; it has not disclosed the relevant error path or the data exposed. Exploitation requires local access and low privileges, needs no user interaction, and affects confidentiality without reported data modification or service interruption.
