Changes from v1:

Stats query was passing in a pointer-to-pointer and storing pointer to 
global adminq response buffer as output parameter, so changing that to a 
local buffer resulted in storing a pointer to a buffer that was stack 
allocated (i.e. introduced a use-after-free).

I've changed that to allocate the stats structure on the stack and write 
into that, instead of returning a pointer to output buffer and reading 
from it.
