Overview
Recent academic research has revealed multiple GPU-targeted RowHammer attacks exploiting GDDR6 memory vulnerabilities. The most notable, GPUBreach, demonstrates how bit flips induced in GPU memory can corrupt critical page tables, enabling attackers to escalate privileges to the system root level and achieve full CPU control. This attack advances prior GPU RowHammer methods by bridging GPU memory corruption to host CPU compromise, underscoring a new threat vector in system security.
