    Summary: Uninitalized memory read & leak caused by fuser crate

    Details: During creation of new libfuse session with `fuse_session_new` operation list was passed as NULL incorrectly. libfuse expects this argument to always point to list of operations. This caused uninitialized memory read and leaks in libfuse.so
