Vulnerability CVE-2023-44216


Published: 2023-09-27

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.
