How to Fix GHSA-jf5h-cf95-w759

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.

raw-cpuid fixed: 9.1.1 
Upgrade raw-cpuid to 9.1.1
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 raw-cpuid

How to Check if You Are Affected

To determine whether your application is affected by GHSA-jf5h-cf95-w759, 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 9.1.1), 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 General Security Weakness. 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.

Source Advisory Statement

When activating the non-default feature `serialize`, most structs implement `serde::Deserialize` without sufficient validation. This allows breaking invariants in safe code, leading to: * Undefined behavior in `as_string()` methods (which use `std::str::from_utf8_unchecked()` internally). * Panics due to failed assertions. See https://github.com/gz/rust-cpuid/issues/43.
