LeapFrog: The Rowhammer Instruction Skip Attack

arXiv:2404.07878v1 Announce Type: new
Abstract: Since its inception, Rowhammer exploits have rapidly evolved into increasingly sophisticated threats not only compromising data integrity but also the control flow integrity of victim processes. Nevertheless, it remains a challenge for an attacker to identify vulnerable targets (i.e., Rowhammer gadgets), understand the outcome of the attempted fault, and formulate an attack that yields useful results.
In this paper, we present a new type of Rowhammer gadget, called a LeapFrog gadget, which, when present in …
