For the NVIDIA Quadro, NVS, and GeForce products, NVIDIA Windows GPU Display Driver R340 before 342.00 and R375 before 375.63 contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgDdiEscape ID 0x600000D where a value passed from a user to the driver is used without validation as the index to an internal array, leading to denial of service or potential escalation of privileges.
The DxgkDdiEscape handler for 0x600000D passes an unchecked user provided pointer as the destination for a memcpy call. This leads to kernel memory corruption.
