Notable parts:<p>- "GPU users should understand that the only cards known to be vulnerable to Rowhammer are the RTX 3060 and RTX 6000 from the Ampere generation"<p>- mitigations are enabling ECC on the GPU or enabling IOMMU in BIOS<p>So doesn't sound like a big deal for users, this is more of a datacenter sort of vulnerability. The fact that this attack is possible at all (you can turn small GPU memory writes into access to <i>CPU</i> memory) is pretty shocking to me, though.
