Kernel-memory disclosure to local low-privileged users
Published Nov 14, 2023 · Updated Oct 8, 2025
Information disclosure in the Windows kernel allows local users with low privileges to read sensitive kernel memory on affected Windows releases. Microsoft identifies improper access control but has not published the specific kernel routine or operation that exposes the memory. Exploitation requires local low-privileged access and no user interaction; the reported consequence is confidentiality loss only, without integrity or service impact.
