You can try to use gdb or similar tools to figure out more about it [1].

Since I am missing information and you don't have a working reproducer - how should I then fix anything? Your comment from the first doesn't seem to apply and it is unclear how you came to the conclusion in the first place. > > Can you reproduce it with it? > > Sorry. The above syzkaller reproducer needs the additional support to run it. > But here is a C reproducer: > https://gist.github.com/freexxxyyy/0be5002c45d7f060cb599dd7595cab78 I've tried to run it with the normal syz-execprog - but you seem to say now that this reproducer is not working the upstream one? In this case, please try to get it working with upstream. See also the mail from Kees Cook [2].
