Vulnerability Title
WAMR runtime hangs or crashes with large memory.fill addresses in LLVM-JIT mode
Vulnerability Description
WebAssembly Micro Runtime (WAMR) is a lightweight standalone WebAssembly (Wasm) runtime. In WAMR versions prior to 2.4.2, when running in LLVM-JIT mode, the runtime cannot exit normally when executing WebAssembly programs containing a memory.fill instruction where the first operand (memory address pointer) is greater than or equal to 2147483648 bytes (2GiB). This causes the runtime to hang in release builds or crash in debug builds due to accessing an invalid pointer. The issue does not occur in FAST-JIT mode or other runtime tools. This has been fixed in version 2.4.2.

WebAssembly Micro Runtime 安全漏洞
Vulnerability Description
WebAssembly Micro Runtime（WAMR）是Bytecode Alliance开源的一种轻量级的独立 WebAssembly 运行时。具有占用空间小、高性能和高度可配置的功能，适用于从嵌入式、物联网、边缘到可信执行环境 (TEE)、智能合约、云原生等应用程序。 WebAssembly Micro Runtime 2.4.2之前版本存在安全漏洞，该漏洞源于在LLVM-JIT模式下执行内存填充指令时处理不当，可能导致运行时挂起或崩溃。
