Description
win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP3 does not properly validate the arguments to functions, which allows local users to read arbitrary data from kernel memory via a crafted application that triggers a NULL pointer dereference, aka "Win32k Incorrect Parameter Validation Allows Information Disclosure Vulnerability."
