According to https://syzkaller.appspot.com/bug?id=d50670eeb21302915bde3f25871dfb7ea43db1e4 there is a way how to test it, many reports and the last one about a week old. Is there a way to instruct syzbot to run the same tests on a given branch? (The reproducer is basically setting up environment with limited amount of memory available for allocation and this hits the BUG_ON.)
