Mitigate CopyFail (CVE-2026-31431), DirtyFrag (CVE-2026-43284) and Fragnesia (CVE-2026-46300) vulnerabilities in the Linux Kernel using a simple but effective Ansible playbook.
Use this Ansible Playbook to run against your servers or groups. The target extra vars option is what you want to use with the host or group entries from your Ansible inventory.
Example:
ansible@ansible:~$ ansible-playbook mitigate-copyfail-dirtyfrag.yaml --extra-vars "target=all_linux"

Contributions and improvements welcome, but lets stick to these two vulnerabilities. This playbook is a quick-fix to share and it is not the plan to make it a "cover all the vulnerabilities" playbook.
