Attempt to exploit the meltdown attack

Instructions

Kernel Module to store the data

1. Run make to generate the Kernel module

$make

2. Run insmod to insert it

$ sudo insmod KernelModule.ko

3. Check the address of the data

$tail /var/log/kern.log

4. Note down the value in the statement

Secret data address = <value>

5. In OutofOrderExecution.c replace the value of kernel_addr with the above.

unsigned long kernel_addr = 0xfab3b024;

Replace 0xfab3b024 with the value obtained.

Run the attack

1. Compile the "OutofOrderExecution.c" file

gcc -march=native -o OutofOrder OutofOrderExecution.c

2. Run OutofOrderExecution

./OutofOrder
