VU#446598: GPU kernel implementations susceptible to memory leak

Overview

General-purpose graphics processing unit (GPGPU) platforms from AMD, Apple, and Qualcomm fail to adequately isolate process memory, thereby enabling a local attacker to read memory from other processes. An attacker with access to GPU capabilities using a vulnerable GPU's programmable interface can access memory that is expected to be isolated from other users and processes.

Description

Graphics processing units (GPUs), originally used to accelerate computer graphics, have today become the standard hardware accelerators for scientific computing and articifical intelligence …
