ETH Zurich reports that researchers from the Vrije Universiteit Amsterdam and Qualcomm Technologies found flaws within DRAM chips. The article I’m linking to is more of an announcement; ETH Zurich tells me the full results will be presented at IEEE in 2022.
It means that by repeatedly activating – or “hammering” – a memory row (the “aggressor”), an attacker can induce bit errors in a neighbouring row, also called the “victim” row. That bit error can then, in principle, be exploited to gain access to restricted areas inside the computer system – without relying on any software vulnerability.
