Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Linux/Linux, Linux/Linux, linux/linux_kernel.
  2. 2Review the reported fix. Update Linux/Linux to 480469f145e5abf83361e608734e421b7d99693d; linux/linux_kernel to 2dcda336b6e8 if you use the affected versions. Test the change in a non-production environment first.
