Summary:
- The article discusses a new variant of the Rowhammer attack, called GPUHammer, which targets the graphics processing unit (GPU) instead of the traditional CPU.
- Rowhammer is a hardware vulnerability that allows an attacker to gain unauthorized access to a system by repeatedly accessing specific memory locations, causing bit flips in adjacent memory cells.
- The GPUHammer attack can be used to bypass security measures and gain access to sensitive information stored on the GPU, which is often used for tasks like machine learning and cryptocurrency mining.
