Rowhammer Attacks Now Target NVIDIA High-End GPUs

Researchers from the University of Toronto have demonstrated that Rowhammer attacks, previously known to affect standard DRAM, can now target GDDR6 memory on NVIDIA's high-end GPUs when ECC is disabled. This vulnerability exploits a memory bug where repeated access to one memory row causes bit flips in another. NVIDIA recommends enabling ECC for protection, especially crucial for data center admins and workstation users. While newer memory types like GDDR7 and HBM3 have built-in OD-ECC, many users disable ECC for performance or configuration reasons, increasing their risk. Check your ECC status now if unsure!
