Here's something we missed with the latest NVIDIA driver updates - turns out that NVIDIA had multiple security issues that they put out in a recent security bulletin. Multiple issues affect both Windows and Linux, across multiple versions of the official NVIDIA proprietary driver.
The ones that affect the Linux desktop are:
- CVE‑2021‑1052: "NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape or IOCTL in which user-mode clients can access legacy privileged APIs, which may lead to denial of service, escalation of privileges, and information disclosure."
- CVE‑2021‑1053: "NVIDIA GPU Display Driver for Windows and Linux contains a vulnerability in the kernel mode layer (nvlddmkm.sys) handler for DxgkDdiEscape or IOCTL in which improper validation of a user pointer may lead to denial of service."
- CVE‑2021‑1056: "NVIDIA GPU Display Driver for Linux contains a vulnerability in the kernel mode layer (nvidia.ko) in which it does not completely honor operating system file system permissions to provide GPU device-level isolation, which may lead to denial of service or information disclosure."
There's also some vGPU security issues too, which also affect Linux but they're not regular desktop stuff.
If you want to make sure you're totally safe you should update to the latest driver in the series you're using. Going by the information on the NVIDIA security page you should be good on (or better) 460.32.03 which is the latest "Production Branch" driver, 450.102.04 and 390.141 being the latest Legacy driver.
You can look out for future security info here from NVIDIA.

Quoting: aokamiNah, the rendering is done by the browser and through the compositor. You'd likely have to run a rogue application or a very badly designed rendering application that'd run arbitrary code. I'll try to go get some more information.Interesting, thanks. While my question was a bit hyperbolic, I'm glad to learn about things like this.
Fun fact: simple stuff taken for granted like jpg libraries had countless vulns and exploit in older versions, and carefully crafted image files could have been detrimental.

Quoting: PhiladelphusI remember first reading about that and couldn't help but wonder how one would not notice a corrupted image with a payload, but ehen looking into it, sure enough it was possible simply because of the way jpg worked.
