Date: Tue, 31 Oct 2017 09:24:39 -0400	[thread overview]
Message-ID: <CAASgV=tSiiiXgCzuk03AyvrLS72zJxzF1rL4JkFgLnxBDzqhug@mail.gmail.com> (raw)

Hi,

We got the following error:

BUG: KASAN: use-after-free in move_expired_inodes+0xce6/0xdf0
Write of size 8 at addr ffff8800a3a36bf8 by task kworker/u8:0/5

while fuzzing with Syzkaller on 4.14-rc4 on x86_64. Included is the
trace of the crash along with the programs running around the time of
the crash.

Programs can be found here: https://pastebin.com/RYGtNn3z

Stack trace here: https://pastebin.com/SaJXWMg3

We don't have a C reproducer but we will send one if we have it.

Regards,
Shankara
