Nvidia's GPUs Vulnerable to Rowhammer Attack
Introduction
Nvidia, a leading manufacturer of GPUs, has fallen victim to the Rowhammer bit-flip attacks. This type of attack targets the onboard memory of GPUs and is the first of its kind. The repercussions of this attack could be far-reaching and potentially impact other GPUs in the future.
Current Scenario
Rowhammer attacks use a technique that repeatedly accesses specific rows of memory in order to cause bit flips in neighboring rows. This creates a vulnerability in the memory system and can lead to unauthorized access or data corruption. While this attack has primarily targeted computer processors, it has now extended to GPUs. Nvidia's GPUs are known for their high performance and are widely used in gaming and data processing, making them a prime target for attacks.
