✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 Workaround: If the `guest-ssh-add-authorized-keys` command is not required, it can be disabled by adding it to the qemu-guest-agent block list (qemu-ga --block-rpcs). This prevents the vulnerable code path from being reached while preserving all other guest-agent functionality.
