Description

A flaw was found in Wasmtime, a runtime for WebAssembly. This vulnerability allows for a use-after-free condition when a host application incorrectly clones and then drops a `wasmtime::Linker` instance before its cloned counterpart is used. This can lead to unpredictable program behavior and potentially result in a denial of service.
