Mayhem: Targeted Corruption of Register and Stack Variables

arXiv:2309.02545v2 Announce Type: replace
Abstract: In the past decade, many vulnerabilities were discovered in microarchitectures which yielded attack vectors and motivated the study of countermeasures. Further, architectural and physical imperfections in DRAMs led to the discovery of Rowhammer attacks which give an adversary power to introduce bit flips in a victim's memory space. Numerous studies analyzed Rowhammer and proposed techniques to prevent it altogether or to mitigate its effects.
In this work, we push the boundary and show how Rowhammer …
