Summary
Wasmtime, the WebAssembly runtime used to execute WebAssembly code in applications and services, is affected by this flaw, which involves confusion between types when struct types with supertypes are created by the host and used across different engines. The impact is that the runtime may mishandle type checks, which could potentially allow memory-safety issues or incorrect behavior when untrusted WebAssembly code runs.
