Out-of-bounds Read

Overview Affected versions of this package are vulnerable to Out-of-bounds Read in the preservelocalforblock function, when handling a sequence where a GETGLOBALI32 opcode is followed by an if opcode in fast interpreter mode. An attacker can cause out-of-bounds access to the frameoffsetbottom arr...

CVE-2025-64713 WebAssembly Micro Runtime frame_offset_bottom array bounds overflow in fast Interpreter mode when handling GET_GLOBAL(I32) followed by if opcode
