WebIn the spectre paper, there is an example which exploits an out of bound array access (Section 1.2). The code is if (x < array1_size) y = array2 [ array1 [x] * 256 ]; The process is to train the correct path with some valid x values. Then an invalid value of x is given and the same time assume arra1_size is uncached.
