Researchers at Google have identified a new Rowhammer technique, dubbed Half-Double, which exploits design flaws in modern DRAM chips to alter their memory content. Rowhammer is a DRAM vulnerability in which repeated access to one address can tamper with data stored in other addresses. Google researchers observed Rowhammer effects propagating to rows beyond adjacent neighbors, albeit at a reduced strength. The researchers say it significantly advances the understanding of the Rowhammer phenomenon, and it will help both researchers and industry partners work together to develop lasting solutions.”]
