RowHammer is a DRAM vulnerability that can cause bit errors in a victim DRAM
row by just accessing its neighboring DRAM rows at a high-enough rate. Recent
studies demonstrate that new DRAM devices are becoming increasingly more
vulnerable to RowHammer, and many works demonstrate system-level attacks for
privilege escalation or information leakage. In this work, we leverage two key
observations about RowHammer characteristics to spy on DRAM temperature: 1)
RowHammer-induced bit error rate consistently increases (or decreases) as the
temperature …
