CVE-2023-26489

wasmtime is a fast and secure runtime for WebAssembly. In affected versions wasmtime's code generator, Cranelift, has a bug on x8664 targets where address-mode computation mistakenly would calculate a 35-bit effective address instead of WebAssembly's defined 33-bit effective address. This bug mea...

CVE-2023-26489

Summary of CVE-2023-26489 (wasmtime/Cranelift): In x86_64, Cranelift’s address-mode computation could extend a 32-bit WebAssembly address to 64 bits, producing an effective address up to 35 bits away from linear memory. With default codegen, this allowed wasm-controlled loads/stores to read/write...
