Have you ever heard about driver vulnerability? This article explains what it is and how to avoid the possible security risks.

In 2020, People are more conscious about their digital security. So, Various news on hardware or software vulnerability becomes viral. People also take these things seriously. We have heard about the recent Intel and AMD processor’s security flaws in recent days. We also often see news on various software bugs and security threats. But, Have we ever thought about the PC drivers’ security flaws? Have we ever took the initiative to get rid of risks? The answer may be yes for a few users. But, For the majority, It is No!

Like any other software, your PC drivers also may have some security concerns. That vulnerability can open a path to the attackers. That can cause unrecoverable harm. But, Don’t worry. This article is all about this. You will get to know about the driver vulnerability and some tips to fix it.

What is Driver Vulnerability?

Before knowing it, you should have a clear idea about the drivers. A device driver or a hardware driver on a computer is a type of software that helps hardware to communicate with the operating system. So, When you install an operating system to a new computer, it may not work properly without an update. That update installs the necessary drivers. However, It always may not happen. You may need to manually install any specific driver. Sometimes, this driver may contain some security flaws. It makes your computer open to attackers. It is called driver vulnerability.

An extremely outdated driver software also can be a reason for vulnerability. Else, You may have been using a device that has been discontinued a long time ago. The manufacture may no longer release drivers for that device. That brings a lot of risks. Another reason can be something from the manufacture. They may have released a driver which has security flaws. Attackers may use these weaknesses to do their evil jobs.
