* If you are using "GRUB 2" (default since August 2018), your Linode will boot with the kernel in the OS disk image. However, if you are [still using one of our kernels to boot](https://techdocs.akamai.com/cloud-computing/docs/manage-the-kernel-on-a-compute-instance), the latest kernel configuration (version 7.0.3) contains the patch for the vulnerability. Older Linode provided kernel configurations (e.g., "6.15.7-x86_64-linode169") remain vulnerable. Customers using these configurations are strongly encouraged to switch to the latest kernel and reboot, or use "GRUB 2" to boot from their own kernel on their primary disk, which has been Linode's default boot option since 2018.
