Nvidia chips hacked, fall victim to Rowhammer bit-flip attacks; here’s how to secure the AI GPUs

Canadian researchers have discovered a vulnerability, named GPU Hammer, in Nvidia A6000 GPUs, enabling Rowhammer bit-flip attacks. This attack allows malicious users to sabotage AI models by tampering with data, potentially degrading model accuracy significantly. Nvidia suggests enabling System-Level ECC as a simple fix, especially in multi-tenant environments where simultaneous GPU access is required for the attack.
