The first practical demonstration (POC) confirms that Rowhammer-style memory attacks can effectively target GPU memory. NVIDIA, meet GPUHammer.

A study from the University of Toronto has revealed that modern graphics processing units (GPUs) are susceptible to Rowhammer-style memory attacks, challenging long-held assumptions about the security of GPU memory. The attack, named GPUHammer, represents the first practical demonstration of a Rowhammer exploit targeting high-performance, discrete GPUs, specifically those utilizing GDDR6 memory.
