GDDRHammer and GeForge: New GPU Rowhammer Attack for Root Shell Access

The post announces a new attack method called GDDRHammer and a tool named GeForge, which exploit GDDR6 GPU memory via a Rowhammer-style vulnerability. The attack can escalate privileges to achieve a root shell on affected systems. The research is scheduled for presentation at IEEE S&P 2026, and exploit code is publicly available.
