GPUBreach is a new exploit using RowHammer-style bit-flips in GPU GDDR6 memory to corrupt host kernel data and achieve full system control.

How does GPUBreach work on GPUs?

Attackers hammer GPU memory rows to flip bits in DMA-accessible host pointers, enabling privilege escalation from a GPU compute task.

Is my NVIDIA GPU vulnerable to GPUBreach?

Older cards like A100 and RTX 30-series yes; check vendor advisories for patches, but full mitigation requires hardware changes.

📋 Compliance & Policy

Forget data leaks — GPUBreach turns GPU glitches into total system domination. Researchers just proved RowHammer isn't just a CPU headache anymore.
