New GPUThor Rowhammer Defeats ECC on NVIDIA RTX A6000 to Gain Host Root Accesshttps://thehackernews.com/2026/08/gputhor-rowhammer-defeats-ecc-on-nvidia.html
Academic researchers have disclosed a Rowhammer attack impacting NVIDIA workstation GPUs with GDDR6 memory that defeats error correction codes (ECC), the mitigation NVIDIA recommends against GPU Rowhammer, and enables denial-of-service (DoS) and privilege escalation to a root shell. Dubbed GPUThor, the attack was developed by researchers at the University of Toronto, who hammered four DRAM
