No. I've run the Rowhammer test in memtest86 on my PC after building it (as part of the whole memtest package to verify my XMP was stable) and got zero errors on 64GB of DDR5 memory over all the passes. If Memtest couldn't do it when trying its hardest to brute force it nobody doing drive-by javascript has any chance to exploit it.
- userbinator 3y agoCould you tell us what DIMMs you're using? I thought Rowhammer-free RAM was a thing of the past, but if some manufacturer has fixed theirs to be immune, they deserve the extra sales and publicity.

This attack seems to work only with AMD Zen processors and not with Intel 12th-14th gen so I suspect DDR5 on intel is still good.
