How to Fix CVE-2021-26306
To remediate this vulnerability, upgrade all affected Raw cpuid 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 raw-cpuid to 9.0.0
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for raw-cpuid
How to Check if You Are Affected
To determine whether your application is affected by CVE-2021-26306, inspect your project dependencies for Raw cpuid:
inspect dependencies for raw-cpuid
Analyze the terminal output to locate any version of Raw cpuid in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 9.0.0), 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-198: Use of Incorrect Byte Ordering, where the product receives input from an upstream component, but it does not account for byte ordering (e.g. big-endian and little-endian) when processing the input, causing an incorrect number or value to be used. In Raw cpuid, 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.
