@gregkh@xxxxxxxxxxxxxxxxxxx @nico@xxxxxxxxxxx  - Thanks for the quick response.
@gregkh@xxxxxxxxxxxxxxxxxxx  - Regarding your question, I don't think
the 1 byte buffer is related to the problem. (  it's just was there in
the initial reproducer the fuzzer created, and I forgot to remove it
while reducing code from the reproducer ).
I think the problem is related to the huge size argument , which
influences  the initialization of "this_round".
