Modern RAM Still Vulnerable to Rowhammer Attacks

Extensive mitigations deployed during the last six years have failed to eliminate modern random-access memory (RAM) cards' vulnerability to Rowhammer exploits, according to researchers at ETH Zurich in Switzerland and Vrije University in the Netherlands.
The investigators said a generic tool named TRRespass that can upgrade Rowhammer attacks to hack RAM cards with Target Row Refresh (TRR) safeguards.
The researchers said, "This triggered an industry-wide effort in addressing the issues raised in this paper. Unfortunately ... it will take a long time before effective mitigations will be in place."
The hardware community has been trying to fix the Rowhammer situation since 2014.
