ntqueryinformationtoken

The tag ntqueryinformationtoken covers a Windows kernel information disclosure vulnerability, CVE-2025-53136, which affects Windows 11 and Windows Server 2022 24H2 builds. This bug stems from changes to the kernel function RtlSidHashInitialize and involves a TOCTOU (time-of-check time-of-use) issue that leaks kernel addresses, undermining KASLR (Kernel Address Space Layout Randomization). The vulnerability creates a timing window where attackers can exploit race conditions to obtain sensitive kernel pointers from userland buffers, potentially enabling local privilege escalation. Discussions focus on the technical details of the exploit, its impact on security defenses, and the risks it poses to enterprise IT environments running affected Windows versions.
