Aarch64

A sandbox escape vulnerability exists in Wasmtime versions 25.0.0 to 36.0.7, 37.0.0 to 42.0.2, and version 43.0.0 when using the Winch compiler backend on aarch64 architecture, potentially allowing a Wasm guest to access host memory outside its sandbox, leading to denial of service, data leaks, or remote code execution.

A critical sandbox escape vulnerability exists in Wasmtime's Cranelift compilation backend on aarch64, allowing guest WebAssembly modules to bypass bounds checks and achieve arbitrary read/write access to host memory under specific configuration conditions.
