What is CVE-2019-5666?

The NVIDIA Windows GPU Display Driver has a vulnerability in the kernel mode layer (nvlddmkm.sys) related to the DxgkDdiCreateContext command. It improperly handles untrusted input when computing or using an array index, leading to potential denial of service or escalation of privileges. This issue arises from inadequate validation of the index, allowing it to reference invalid array positions, thus exposing the system to security risks. Users of the driver are advised to update to the latest version to mitigate these risks.
