Suppose you have access to certain memory. If you repeatedly read from that memory, can't you still corrupt/alter the physically adjacent memory you don't have access to? Does it really need to be a write operation you repeatedly perform? |

Yes. The core of rowhammer attacks is in changing the values in RAM repeatedly, creating a magnetic field, which induces a change in the state of nearby cells of memory. Reading memory doesn't do that as far as I know.
