Preventing Rowhammer Exploits via Low-Cost Domain-Aware Memory Allocation
Anish Saxena, Walter Wang, Alexandros Daglis
Rowhammer is a hardware security vulnerability at the heart of every system with modern DRAM-based memory. Despite its discovery a decade ago, comprehensive defenses remain elusive…
ImPress: Securing DRAM Against Data-Disturbance Errors via Implicit Row-Press Mitigation
Moinuddin Qureshi, Anish Saxena, Aamer Jaleel
DRAM cells are susceptible to Data-Disturbance Errors (DDE), which can be exploited by an attacker to compromise system security. Rowhammer is a well-known DDE vulnerability that o…
Randomized Line-to-Row Mapping for Low-Overhead Rowhammer Mitigations
Anish Saxena, Saurav Mathur, Moinuddin Qureshi
Modern systems mitigate Rowhammer using victim refresh, which refreshes the two neighbours of an aggressor row when it encounters a specified number of activations. Unfortunately,…
Scalable and Configurable Tracking for Any Rowhammer Threshold
Anish Saxena, Moinuddin Qureshi
The Rowhammer vulnerability continues to get worse, with the Rowhammer Threshold (TRH) reducing from 139K activations to 4.8K activations over the last decade. Typical Rowhammer mi…
