How to Fix GHSA-jf43-3v8j-qwwr

To remediate this vulnerability, upgrade all affected Multiqueue dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

multiqueue fixed: Latest secure release 
Upgrade multiqueue to Latest secure release
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for multiqueue

How to Check if You Are Affected

To determine whether your application is affected by GHSA-jf43-3v8j-qwwr, inspect your project dependencies for Multiqueue:

inspect dependencies for multiqueue

Analyze the terminal output to locate any version of Multiqueue in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'), where the product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently. In Multiqueue, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Affected versions of multiqueue unconditionally implemented `Send` for types used in queue implementations (`InnerSend<RW, T>`, `InnerRecv<RW, T>`, `FutInnerSend<RW, T>`, `FutInnerRecv<RW, T>`). This allows users to send non-Send types to other threads, which can lead to data race bugs or other undefined behavior.
