GPU Security Crisis: Rowhammer Attacks Now Enable Complete Server Takeover

Rowhammer attacks, which have targeted CPU memory for over a decade, have now evolved to compromise Nvidia GPUs used in shared cloud environments. Since these high-performance GPUs cost $8,000 or more and serve multiple users simultaneously, successful attacks give malicious actors full root control over shared cloud infrastructure. This development significantly expands the attack surface for cloud providers and marks a critical escalation in hardware vulnerability exploitation.
