Nope! Or not completely true.

https://bugs.gentoo.org/show_bug.cgi?id=597554#c56
where find:

"which means, with SANITIZE: crash, w/o SANITIZE: no work..."

And also my recall in the next comment, the c57 of how previously even
the SANITIZE-disabled kernel crashed.

Wish I could dedicate more time to that testing now... Unfortunately,
no straight dedicated long enough time to work on that available here
for one or two more days...

Binary search should be in order...

And your reply in that bug, to how that different behavior of those
kernel, for non-experts would be great... (the "ioctl(KVM_CREATE_VM)
failed: 12 Cannot allocate memory"... by SANITIZE-disabled kernel...

Of course, if you can find that time... (esp. since I can not find much
time now for a while)...

Regards!
