How to Fix CVE-2022-23066

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

solana_rbpf fixed: 0.2.28 
Upgrade solana_rbpf to 0.2.28
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 solana_rbpf

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-23066, inspect your project dependencies for Solana rbpf:

inspect dependencies for solana_rbpf

Analyze the terminal output to locate any version of Solana rbpf in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.2.28), 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-682: Incorrect Calculation, where the product performs a calculation that generates incorrect or unintended results that are later used in security-critical decisions or resource management. In Solana rbpf, 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

In Solana rBPF versions 0.2.26 and 0.2.27 are affected by Incorrect Calculation which is caused by improper implementation of sdiv instruction. This can lead to the wrong execution path, resulting in huge loss in specific cases. For example, the result of a sdiv instruction may decide whether to transfer tokens or not. The vulnerability affects both integrity and may cause serious availability problems.
