Detailsinfo

A vulnerability classified as problematic was found in bytecodealliance wasm-micro-runtime up to 2.4.1. Affected by this vulnerability is an unknown function. The manipulation with an unknown input leads to a untrusted pointer dereference vulnerability. The CWE definition for the vulnerability is CWE-822. The product obtains a value from an untrusted source, converts this value to a pointer, and dereferences the resulting pointer. As an impact it is known to affect availability. The summary by CVE is:

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.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-58749 since 09/04/2025. The exploitation appears to be easy. An attack has to be approached locally. Neither technical details nor an exploit are publicly available.
