github.com/snapcore/snapd fixed: 2.57.6 
Upgrade github.com/snapcore/snapd to 2.57.6
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 github.com/snapcore/snapd

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-3328, inspect your project dependencies for Github.com/snapcore/snapd:

inspect dependencies for github.com/snapcore/snapd

Analyze the terminal output to locate any version of Github.com/snapcore/snapd in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.57.6), 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 Github.com/snapcore/snapd, 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.
