Disable heap randomization
configname: CONFIG_COMPAT_BRK
Linux Kernel Configuration
└─>Memory Management options
└─>Disable heap randomization
In linux kernel since version 5.2 (release Date: 2019-07-07)
Randomizing heap placement makes heap exploits harder, but it
also breaks ancient binaries (including anything libc5 based).
This option changes the bootup default to heap randomization
disabled, and can be overridden at runtime by setting
/proc/sys/kernel/randomize_va_space to 2.
On non-ancient distros (post-2000 ones) N is usually a safe choice.
