Summary
FUSE-Rust: Uninitalized memory read and leak caused by fuser crate
Details

During the creation of a new libfuse session with fuse_session_new, the 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.

Severity ?
8.2 (High)
