CVE-2023-44216 Information

Description

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. 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.
