CVE-2021-32629
Cranelift’s x64 backend bug in 0.73 (and certain earlier builds when the new backend is explicitly selected) can sign-extend a loaded i32 value, potentially enabling sandbox escapes in Wasm modules and exposing memory up to 2 GiB before the heap. Wasmtime and Lucet using Cranelift may be exploita...
