CVE-2022-31146

CVE-2022-31146 affects Wasmtime (Cranelift) in the migration to the regalloc2 allocator (Wasmtime 0.37.0). The bug may cause metadata for reference-typed functions to be missing during GC, making the GC pass think there are no live references, leading to use-after-free when values are later acces...
