The attached testcase crashes Windows 7 32-bit due to a pool buffer overflow in an ioctl handler. Enabling special on ndis.sys netio.sys and ntoskrnl helps to track down the issue, however it will crash due to a bad pool header without special pool as well.

The 3D Vision service nvSCPAPISvr.exe installed as part of typical driver installations runs at Local System and has an insecure named pipe server. One of the commands in the server can be used to set an Explorer Run key for the system which would allow a user to get code executing in the session of any other user who logs on to the same machine leading to elevation of privilege. In Windows Domain environments it would also be possible to exploit the vulnerability between machines if the attacker has access to a valid user account on one domain joined machine.

The attached poc crashes 32-bit Windows 7 with a screen resolution of 1024×768 and 32bit color depth. The crash occurs during a memmove operation while copying the cursor content from unmapped memory. This could potentially be used by an attacker to leak kernel memory. When reproducing this issue in VMWare, it is necessary to remove VMWare tools. In QEMU the issue reproduces reliably.

The attached testcase crashes Window 7 32-bit with Special Pool enabled on win32k.sys due to a use-after-free condition. The bug appears to be a race condition between two threads and multiple runs on the PoC might be required to trigger the bug. This is more reliable on systems with multiple cores.
