What is github.com/tklauser/numcpus's Vulert package health score?
Vulert scores github.com/tklauser/numcpus 63/100, which reads as usable, but worth attention. The score weighs the vulnerability record (40), maintenance and release cadence (25), adoption from dependents and stars (20) and community signals such as the OpenSSF scorecard and forks (15).

How often are new github.com/tklauser/numcpus vulnerabilities disclosed?

Which versions of github.com/tklauser/numcpus are affected?
Each vulnerability on this page lists the affected version range and the fixed version to move to. Open the vulnerability for the version you actually run — fixes are specific to a release line, not to the package as a whole.
How do I monitor github.com/tklauser/numcpus for upcoming vulnerabilities?
Upload the manifest or SBOM for your application at vulert.com/scanner and Vulert keeps checking the github.com/tklauser/numcpus version you actually run against new disclosures, then alerts you when one affects it. There is no installation and no source-code access required.
