We provide an overview of recent developments and future directions in the RowHammer vulnerability that plagues modern DRAM (Dynamic Random Memory Access) chips, which …
DRAM is the building block of modern main memory systems. DRAM cells must be periodically refreshed to prevent data loss. Refresh operations degrade system performance …
To understand and improve DRAM performance, reliability, security, and energy efficiency, prior works study characteristics of commodity DRAM chips. Unfortunately, state-of-the-art …
Despite nearly decade-long mitigation efforts in academia and industry, the community is yet to find a practical solution to the Rowhammer vulnerability. Comprehensive software …
Backdoor attacks have raised significant concerns in machine learning (ML) systems. Mainstream ML backdoor attacks typically involve either poisoning the victim's training …
The shortcomings of previous Rowhammer mitigations prevent their adoption in practice. Their implementations either need significant amounts of fast memory, such as CAM or …
Today's cloud DRAM lacks strong isolation primitives, highlighted by Rowhammer bit flips. Rowhammer poses an increasing threat to cloud security/reliability, given (1) DRAM …
Global variables in the Linux kernel have been a common target of memory corruption attacks to achieve privilege escalation. Several potential defense mechanisms can be …
