## Technical details

An out-of-bounds read in the Windows DNS Server component allows authenticated remote attackers to read beyond allocated buffer boundaries, potentially disclosing sensitive kernel or application memory. The vulnerability requires administrative or elevated privileges to trigger and is accessed over the network via DNS protocols. Successful exploitation results in information disclosure without enabling code execution or denial of service.
