The truth about Nvidia’s Rowhammer question

Cybersecurity issues are a fact of our lives in the digital age. Some threats More worrying,,,,, There are others Not that big deal As some people make them become. On today’s menu, we’ll discuss Rowhammer, a known utilization that affects dynamic random access memory (DRAM). Specifically, a variant called Gpuhammer uses GDDR6 memory to change the graphics card.

According to toNew research GPUHAMMER is the first Rowhammer variant at the University of Toronto that specifically affects GPUs (graphics processing unit). Research shows that GPUHammer can flip bits on GDDR6 memory, which can cause various problems, including leaking personal data and affecting the GPU’s ability to perform some workflows. For example, the researchers say that even flips can even reduce the accuracy of the deep neural network model from 80% to 0.1%, and the accuracy is further reduced when more bits are flipped. Since NVIDIA GPUs are very popular in data centers and workstation computers, this means this vulnerability could affect many businesses.

Nvidia release Security Notification About utilization. Fortunately, the fix is very simple. All anyone needs to do is enable system-level ECC or correct error codes. This simple setup creates redundancy in the bit, so if a person flips, the system can automatically correct it before any problems arise.

Should I worry about gpuhammer?

In short, no. NVIDIA and researchers agree that this appears to only affect workstations and data center GPUs. The researchers even tried this exploit on the NVIDIA RTX 3080, but couldn’t make it work. So, for our civilians, everything is fine. also, BleepingComputer Commenter Commenter Comment In any case, exploits require conditions that are not usually seen in consumer-grade computers, so even if consumer GPUs can be exploited, the risk of actually happening is low.

If you have a business using NVIDIA workstations or data center GPUs, you will need View the list Affected GPU. If you are above, please follow NVIDIA Guide Used to enable GPU ECC. When enabled, everything should return to normal.
