How to fix?

There is no fixed version for RHEL:10 virt-firmware-rs.

NVD Description

Note: Versions mentioned in the description apply only to the upstream virt-firmware-rs package and not the virt-firmware-rs package as distributed by RHEL. See How to fix? for RHEL:10 relevant fixed versions and status.

Wasmtime 46.0.0 before 48.0.6 and 49.0.0 before 49.0.3 panics when the host reads a component model stream as a different Rust item type than it was created with, because the host-to-host read path asserts matching TypeIds instead of returning an error. Guest code can return a host-created StreamReader<U> that the embedder reads as StreamReader<T>, where both types map to the same component model type, crashing the embedding process.
