Amazon Linux 2027, GitHub Actions Cache Security, Secret-Scanning Merge Blocks, N-central CVSS 10 RCE, Karmada Graduation, ShieldCrash, CodeQL ARM64 & When Observability Fails Too

This week on Ship It Weekly: Amazon Linux 2027 enters public preview with kernel 7.1+, SELinux enforcing by default, DNF5, newer language runtimes, AWS-LC, and an x86-64-v3 baseline. GitHub Actions adds explicit cache permissions to reduce cache-poisoning risk. GitHub can now block pull requests from merging when they introduce exposed secrets. And N-able N-central has a critical pre-auth RCE that Huntress says is being actively exploited in the wild.

The bigger theme this week is catching problems before they turn into incidents. Amazon Linux 2027 gives teams time to test AMIs, bootstrap scripts, agents, Terraform, CloudFormation, and CI/CD before the next platform generation becomes production reality. GitHub’s new cache controls make workflow trust boundaries explicit instead of leaving them implied. And secret-scanning rulesets move credential detection directly into the merge path, where developers can actually act on it.

In the lightning round: Karmada graduates from the CNCF as multi-cluster and distributed AI scheduling grow, ShieldCrash research claims another Microsoft Defender patch bypass with SYSTEM-level access, CodeQL 2.27 adds native Linux ARM64 support, and Dependabot can now read private GitHub Packages without another personal access token.

And the human closer is about what happens when observability shares the same failure domain as the thing it is watching. A full disk is bad enough. It gets worse when logs stop writing, monitoring data disappears, and the tools used to diagnose the outage start failing too. The takeaway is not that every monitoring component needs total isolation. It is that you should know what can blind you, and make sure at least one useful signal survives the failures you care about most.
