CVE-2025-62711 (opens in a new tab)Amendment
This was deemed not a vulnerability.
Overview
cranelift-codegen is a translates code from an intermediate representation into executable machine code.
Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the implementation of component-model related host-to-wasm trampolines. An attacker can cause the host to crash with a segmentation fault or assertion failure by crafting a component and invoking it in a specific manner that abuses the setjmp and longjmp functions in C.
Note: Only embeddings that use or invoke functions with specific component type signatures may be affected.
Note: addressing CVE-2025-62711 for wasmtime required Cranelift refactoring; however Cranelift itself was not vulnerable.
