GPUThor: Amplifying Rowhammer Attacks Via Non-Uniform Patterns to Exploit ECC-Protected GPUs

GDDR memory in GPUs is vulnerable to Rowhammer attacks, where rapid memory accesses induce bit flips in adjacent cells, enabling data tampering and privilege escalation. However, prior GPU Rowhammer attacks trigger only tens to hundreds of bit flips, orders of magnitude fewer than CPU attacks,...
