Description

Windows contains a flaw that may allow a malicious user to gain access to unauthorized privileges. The issue is triggered when the NtSetLdtEntries API function fails to validate user-supplied input, which can then be passed to kernel code which also fails to validate the input. This flaw may allow an attacker to execute arbitrary code in kernel space, and lead to a loss of integrity.
