New ZenHammer memory attack impacts AMD Zen CPUs


Academic researchers developed ZenHammer, the first variant of the Rowhammer DRAM attack that works on CPUs based on recent AMD Zen microarchitecture that map physical addresses on DDR4 and DDR5 memory chips.

AMD Zen chips and DDR5 RAM modules were previously considered less vulnerable to Rowhammer, so the latest findings challenge this notion.

The ZenHammer attack was developed by researchers at public research university ETH Zurich, who shared their technical paper with BleepingComputer.
