CVE-2023-44216

Published: 27 September 2023

PVRIC (PowerVR Image Compression) on Imagination 2018 and later GPU devices offers software-transparent compression that enables cross-origin pixel-stealing attacks against feTurbulence and feBlend in the SVG Filter specification, aka a GPU.zip issue. For example, attackers can sometimes accurately determine text contained on a web page from one origin if they control a resource from a different origin.

Notes

GPU.zip blog posts claims that all GPUs are likely affected
but none responded to it yet.
added nvidia drivers tracking, but later updates will
be necessary for a proper triage over nvidia and other GPUs.

some binary drivers are no longer support by NVidia, so they
are marked as ignored here
