Another Flip in the Wall of Rowhammer Defenses

, 2018
The Rowhammer bug allows unauthorized modification of bits in DRAM cells from unprivileged software, enabling powerful privilege-escalation attacks. Sophisticated Rowhammer countermeasures have been presented, aiming at mitigating the Rowhammer bug or ...

Flipper: Rowhammer on Steroids [PDF]

The density of memory cells in modern DRAM is so high that frequently accessing a memory row can flip bits in nearby rows. That effect is called Rowhammer, and an attacker can exploit this phenomenon to flip bits by rapidly accessing the contents of ...

Understanding RowHammer Under Reduced Wordline Voltage: An Experimental Study Using Real DRAM Devices

, 2022
RowHammer is a circuit-level DRAM vulnerability, where repeatedly activating and precharging a DRAM row, and thus alternating the voltage of a row's wordline between low and high voltage levels, can cause bit flips in physically nearby rows.

Exploiting correcting codes:On the effectiveness of ECC memory against rowhammer attacks

, 2019
Given the increasing impact of Rowhammer, and the dearth of adequate other hardware defenses, many in the security community have pinned their hopes on error-correcting code (ECC) memory as one of the few practical defenses against Rowhammer attacks ...
