I have attached the causing hfs filesystem image, the dmesg report and the source code of a simple mounting tool to reproduce this issue. A local users who have been granted the privileges necessary to mount filesystems (or a system components which auto mounts filesystems) could trigger a null pointer dereference or a kernel panic (depending on panic_on_oops). We can verify this issues for Linux 4.15.0-15.16 (Ubuntu 16.04.4 LTS / sources from "pull-lp-source linux"). The desktop version of ubuntu auto-mounts this file system if provided via USB.
