New Rowhammer technique against DDR5 achieves privilege escalation

Researchers have devised a new technique to trigger Rowhammer bit flips inside the memory cells of DDR5 RAM modules, which were believed to be protected against such attacks. This type of attack allows controlled memory modification leading to privilege escalation exploits or the leaking of sensitive data stored in restricted memory regions. To achieve their new attack, dubbed Phoenix, researchers from ETH Zurich and Google reverse-engineered th…

Modern memory is still vulnerable to Rowhammer vulnerabilities — Phoenix root privilege escalation attack proves that Rowhammer still smashes DDR5 security to bits

A new attack on DDR5 further demonstrates that current countermeasures against Rowhammer-style assaults aren't enough.
