I found it while analyzing several device drivers as a personal hobby. I also want to ask you one question. While analyzing several device drivers, I found several such integer overflow or race condition problems, and made and submitted a patch. https://marc.info/?l=linux-fbdev&m=165497564701256&w=2 https://www.spinics.net/lists/linux-efi/msg24884.html However, there is no response whether this patch has been accepted or rejected. In this case, do I have to send an email to the higher level maintainer? Or do I have to wait? Thanks, Hyunwoo Kim
