How To Disable ASLR

After reading a few comments stating the need to disable ASLR on Ryzen, I decided to disable it.

What is ASLR?

ASLR stands for address space layout randomization, and it is a security technique used to prevent the exploitation of memory corruption vulnerabilities. It randomly arranges the address space positions of key data areas of a process, including the base of the executable and the positions of the stack, heap and libraries.

Steps To Disable ASLR

Run these commands as root.

# disable in current session
echo 0 | tee /proc/sys/kernel/randomize_va_space

# make change permanent (across reboots)
echo "kernel.randomize_va_space = 0" > /etc/sysctl.d/01-disable-aslr.conf
