Chainguard: wasmcloud: security update to 2.10.3-r3

critical Tenable Self-Hosted Container Security Plugin ID 478020

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Wasmtime is a runtime for WebAssembly. Prior to 36.0.19, 48.0.7, and 49.0.4, the Cranelift compiler
 backend on aarch64 can compile a Wasm br_table instruction with more than approximately 256,000 targets so
 that it has an incorrect conditional branch target. The branch can then jump to arbitrary other code at a
 user-controlled offset, allowing a user-controlled Wasm module to escape the sandbox on aarch64 engines
 using the default Cranelift backend. This issue is fixed in versions 36.0.19, 48.0.7, and 49.0.4.
 (CVE-2026-115893)

Solution

Update the wasmcloud library and its related packages to version 2.10.3-r3 or later.
