CVE-2025-64335: Suricata Detect Engine Buffer Null Derefcve-2025-64335-suricata-detect-engine-buffer-null-deref
`DetectEngineBufferTypeGetNameById` can return NULL for registry buffer types like `base64_data`. Passing its result directly into `VarNameStoreRegister` or utilizing it without a NULL validation results in a NULL pointer dereference, crashing the Suricata engine.
