CVE-2025-69261

WasmEdge integer wrap in MemoryInstance::getSpan()'s memory size check

CVSS 5.5 MEDIUMEPSS 0.3%CWE-190

WasmEdge is a WebAssembly runtime. Prior to version 0.16.0-alpha.3, a multiplication in `WasmEdge/include/runtime/instance/memory.h` can wrap, causing `checkAccessBound()` to incorrectly allow the access. This leads to a segmentation fault. Version 0.16.0-alpha.3 contains a patch for the issue.
