GHSA-cvmj-47v9-35m9: FUSE-Rust: Uninitalized memory read and leak caused by fuser crate

September 15, 2025

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.
