Researchers Uncover New GPU Side-Channel Vulnerability Leaking Sensitive Data

A novel side-channel attack called GPU.zip renders virtually all modern graphics processing units GPU vulnerable to information leakage. "This channel exploits an optimization that is data dependent, software transparent, and present in nearly all modern GPUs: graphical data compression," a group...

CVE-2023-44216: Observable Discrepancy

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...
