Rowhammer demonstrated that non-physical hardware-weakness-based attacks can be devastating. In a recent paper, Cai et al.  propose that similar attacks can be performed on MLC NAND flash. In this paper, we discuss the requirements for a successful, full-system, local privilege escalation attack on such media, and show a filesystem based attack vector. We demonstrate the filesystem layer of this attack, showing that a random block corruption of a carefully chosen block is sufficient to achieve privilege escalation. In particular, to motivate the assumptions of this filesystem-level attack, we show the attack primitive that an attacker can obtain by making use of cell-to-cell interference is quite weak, and therefore requires a carefully crafted attack at the OS layer for successful exploitation.
