Patrick Jattke at #hw_ioNL2025 discovered that DDR5’s toughtness comes from clever mitigations—not immunity. Phoenix proves it by adapting to missed refreshes and flipping bits across every tested device.

💾Summarising #MemSec Track at #hw_ioNL2025 for you — it is like a reality show for hardware.
DRAMs flip out, GPUs start gossiping, and memory modules go rogue. Everyone swears their code’s chill… but Rowhammer just made a comeback 😂

DPI risk
Critical systems using DDR5 memory, especially in cloud hosts, government servers, or edge infrastructure, face risk of unauthorized access, data corruption, leaks of cryptographic keys, and undermined trust unless mitigations are rapidly deployed.

CVE-2025-6202: DDR5 "Phoenix" Rowhammer Attack
New Rowhammer variant breaks DDR5 protections.
Bypasses refresh logic → bit flips → data leak / escalation.

New Phoenix RowHammer attack bypasses advanced DDR5 memory protections on SK Hynix chips in just 109 seconds, posing a serious threat. 💥 https://t.co/xOutNX2jD0 #RowHammer #DDR5 #Cybersecurity #MemorySecurity #PhoenixAttack
Researchers revealed the Phoenix attack, a new Rowhammer variant that bypasses TRR defenses in SK Hynix DDR5 memory, allowing bit flips and privilege escalation. All tested modules were vulnerable. #MemorySecurity #HardwareFlaws #SouthKorea

https://t.co/6TMyonmjou Researchers found an easy and inexpensive way to get around new defenses in AMD's Epyc chips to expose data stored in memory. #amdcpuvulnerability #badram #cloudsecurity #memorysecurity
For example, the AgentPoison attack targets RAG-based agents' knowledge base or memory, introducing malicious backdoor triggers. These triggers can cause agents to act unexpectedly or leak sensitive data. 🚨📚https://t.co/adyqq9VM0n #AgentPoison #MemorySecurity 3/7
