Rowhammer on Commodity Operating Systems

Rowhammer on Commodity Operating Systems

Recent years have witnessed an infamous software-induced hardware vulnerability, termed as Rowhammer. Specifically, frequent accesses to the same addresses in DRAM rows can cause bit flips in their adjacent row without accessing the row. If the row contains sensitive data, such as page tables, these bit flips can corrupt the data, posing severe consequences to the whole system security. In this presentation, I will talk about Rowhammer including its attack and defense on commodity OSes.

This presentation is based on the following papers:

[1] Zhang et al. PThammer: Cross-User-Kernel-Boundary Rowhammer through Implicit Accesses, MICRO 2020.
[2] Zhang et al. SoftTRR: Protect Page Tables against Rowhammer Attacks using Software-only Target Row Refresh, ATC 2022.
[3] Zhang et al. SoK: Rowhammer on Commodity Operating Systems, ASIACCS 2024.
