Kernel-memory disclosure to local low-privileged users
Published Jan 12, 2021 · Updated Oct 8, 2024
Information disclosure in the Microsoft Windows Projected File System filter driver allows local users to read kernel memory. Microsoft has not published the faulty operation or input-handling path within the filter driver that exposes the memory contents. Exploitation requires local low-privileged access, needs no action by another user, and affects confidentiality without reported data modification or service interruption.
