26 Sep 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.

09 Nov 2022 — IBPB may not prevent return branch predictions from being specified by pre-IBPB branch targets leading to a potential information disclosure. IBPB no puede evitar que las predicciones de sucursales de retorno sean especificadas por objetivos de sucursales anteriores a IBPB, lo que lleva a una posible divulgación de información. Multiple vulnerabilities have been found in Xen, the worst of which can lead to arbitrary code execution.
