CORTEX Protocol Intelligence Assessment
Business Impact: Kernel-level flaws can enable system instability or elevation of privileges on Ubuntu servers. Technical Context: Patch alignment required across FIPS/RT kernels in production fleets.
Strategic Intelligence Guidance
- Apply the USN kernel updates and reboot impacted hosts.
- Align kernel baselines in automation (MAAS/Ansible).
- Monitor for kernel oops/panics and unusual privilege changes.
- Validate eBPF and RT workloads after patching.
