Just curious: Even after an attacker goes through all the effort of finding out the physical address of the memory location they want to manipulate, how would someone make sure to get an adjacent memory location to even attempt to execute the Rowhammer attack? And even then, the smallest memory units allocated are basically pages within page frames, right? So if your target memory row is within a physical page frame, does the RowHammer attack even work? (Since there's no adjacent row an attacker has access to then.)
