no automatic stack variable initialization (weakest)

configname: CONFIG_INIT_STACK_NONE

Initialize kernel stack variables at function entry
└─>no automatic stack variable initialization (weakest)
In linux kernel since version 5.1 (release Date: 2019-05-05)  
Disable automatic stack variable initialization.
This leaves the kernel vulnerable to the standard
classes of uninitialized stack variable exploits
and information exposures.
