GPU Rowhammer Attacks Beyond Data Corruption (U. of Toronto)


A new technical paper, "GPUBreach: Privilege Escalation Attacks via GPU Rowhammer," was published by researchers at University of Toronto. Summary "GPUBreach shows that GPU Rowhammer attacks can move beyond data corruption to real privilege escalation. By corrupting GPU page tables, an unprivileged CUDA kernel can gain arbitrary GPU memory read/write, and then chain that capability into CPU... » read more
