New ZenHammer Attack Bypasses RowHammer Defenses on AMD CPUs

Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR). "This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack
