New 'GeForge' and 'GDDRHammer' attacks can fully infiltrate your system through Nvidia's GPU memory — Rowhammer attacks in GPUs force bit flips in protected VRAM regions to gain read/write access

Two new Rowhammer attacks for GPUs have been discovered that can cause bit flips in VRAM to gain arbitrary read/write access over it. These attacks target page files and the page directory that are otherwise protected from electrical disturbance by the driver. By "massaging" these data structures into vulnerable regions where a bit flip can occur, the attacker can access even the CPU memory.

Half of planned US data center builds have been delayed or canceled, growth limited by shortages of power infrastructure and parts from China — the AI build-out flips the breakers

As cloud giants plan to spend $650 billion on AI infrastructure this year, the availability of power infrastructure components has become a significant obstacle to deploying AI data centers.
