GHSA-mgg8-9pvp-6qcw at a Glance
How to Fix GHSA-mgg8-9pvp-6qcw
To remediate this vulnerability, upgrade all affected Noise search dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade noise_search to Latest secure release
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for noise_search
How to Check if You Are Affected
To determine whether your application is affected by GHSA-mgg8-9pvp-6qcw, inspect your project dependencies for Noise search:
inspect dependencies for noise_search
Analyze the terminal output to locate any version of Noise search 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 Noise search, 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.

"details" : "Affected versions of the `noise_search` crate unconditionally implement Send/Sync for `MvccRwLock`.\nThis can lead to data races when types that are either `!Send` or `!Sync` (e.g. `Rc<T>`, `Arc<Cell<_>>`) are contained inside `MvccRwLock` and sent across thread boundaries. The data races can potentially lead to memory corruption (as demonstrated in the PoC from the original report issue).\n\nAlso, safe APIs of `MvccRwLock` allow aliasing violations by allowing `&T` and `LockResult<MutexGuard<Box<T>>>` to co-exist in conflicting lifetime regions. The APIs of `MvccRwLock` should either be marked as `unsafe` or `MbccRwLock` should be changed to private or pub(crate).\n",
