Have you downloaded the NVIDIA GeForce Experience (GFE) app? If you have, you need to apply the security update for protection against the Nvidia vulnerability.
It's a helper app designed to work in tandem with GeForce GTX graphics cards. It is designed to automate the process of keeping your drivers up to date and automatically optimize your game settings.
If it's something you rely on, you should be aware that NVIDIA recently discovered a serious security flaw that will require patching in order for you to protect yourself. Tracked as CVE-2019-5702, the flaw allows an attacker to corrupt a system file. In doing so, it allows a potential attacker to escalate privileges to take total control over it, or to trigger a denial of service attack.
If there's a silver lining in the recent discovery, it lies in the fact that in order to exploit the flaw, physical access to your device is required. Given that, it's not as serious a threat as some other recent vulnerabilities. It still represents a genuine threat. That is because the attacks designed to be used in conjunction with the Nvidia vulnerability is of relatively low complexity and require no user interaction.
The flaw impacts any Windows-based PC running NVIDIA GeForce Experience version prior to 3.20.2. If you're using the app, there are two ways to get the update. You can launch the GFE client, which will automatically search for updates and download the latest version. Or you can visit NVIDIA's GeForce Experience Download page and manually download and install the latest version.
Again, while the flaw isn't the most dangerous one we've seen in recent months, it's better to be safe than sorry. So if it's something you rely on to make your gaming experience more convenient and automate the driver update process, the safe bet is to upgrade your way around the flaw. Kudos to NVIDIA for their rapid resolution of the issue.
