Nvidia has addressed a series of significant security vulnerabilities
With over 200 million gamers depending on Nvidia graphics for their gaming enjoyment on both Linux and Windows systems, it’s critical to take security advisories seriously. Especially when the warning pertains to eight new high-severity vulnerabilities; only a careless gamer would overlook this. Here’s what you should know about the Nvidia security vulnerabilities identified as CVE‑2024‑0117 through CVE‑2024‑0121.
Nvidia has released an advisory bulletin outlining eight high-severity common vulnerabilities and exposures, also known as CVE-rated security vulnerabilities. These vulnerabilities affect users with Nvidia graphics processing units on both Linux and Windows platforms, specifically within the GPU display driver and the virtual GPU software.
The urgency of this Nvidia security alert, as explained by the company, stems from the potential consequences for users: code execution, denial of service, privilege escalation, information leakage, and data modification. And if that sounds alarming, it certainly is.
Out-of-bounds memory vulnerabilities arise when a program tries to access data from a memory location that goes beyond an allocated buffer. These vulnerabilities are among the most frequently identified security issues, yet their prevalence shouldn’t imply they are without serious consequences. In the recent Nvidia security advisory, many of the highlighted vulnerabilities seem to reside in the user layer mode of the GPU display driver, and if successfully exploited, they could permit an unprivileged attacker to execute an out-of-bounds read, resulting in the previously mentioned impacts.
Within the vGPU software, two vulnerabilities have been identified, affecting the kernel driver and the virtual GPU manager across all compatible hypervisors. The vGPU kernel vulnerability pertains to improper input validation that endangers the guest OS kernel. In contrast, the vulnerability in the virtual GPU manager software allows a user operating within the guest OS to gain access to global resources.
Nvidia advises, “To safeguard your system, download and install this software update through the NVIDIA Driver Downloads page.” The update to address the vGPU vulnerabilities can be accessed through the Nvidia licensing portal.
The Nvidia security updates for the GPU display driver across different Windows driver branches are documented in the following table; you can navigate to the complete original on Nvidia’s security bulletin site, which also includes the full table for the Linux driver branch.
