Summary

• record the newest functionally validated Ubuntu, AlmaLinux, CentOS Stream, Rocky, Amazon Linux 2, and Amazon Linux 2023 kernels
• record exact Oracle UEK8 6.12.0-204.92.4.4 after signed-package installation, reboot, BPF attach, and execve trace validation
• preserve RHEL as explicitly uncovered because it requires a BYO subscription
