GHSA-75JP-VQ8X-H4CQ Wasmi Out-of-bounds Write for host to Wasm calls with more than 128 Parameters

Summary In the WASMI Interpreter, an Out-of-bounds Buffer Write will arise arise if the host calls or resumes a Wasm function with more parameters than the default limit 128, as it will surpass the stack value. This doesn’t affect calls from Wasm to Wasm, only from host to Wasm. Impact After...
