Kernel information disclosure to local low-privileged users
Published Aug 9, 2022 · Updated Jun 24, 2025
Information disclosure in Microsoft Windows kernel releases allows local users to read sensitive kernel memory via an unspecified flaw. Microsoft has not publicly described the affected kernel component or the operation on untrusted input. Local low-privilege access is required, and the reported consequence is confidentiality loss without integrity or availability impact.
