You can look at the manifest for the kernel:

If you read the description above, you find:

"Fix: The issue was fixed in kernel version 4.13.0-21 by configuring the kernel so it is not compiled with Intel SPI support."

Looking on Launchpad for the linux source package (try !upkg linux in DuckDuckGo), you can see 4.13.0-21.24 is in security for artful. Looking at its [info page][1] one finds a changelog entry:

" * Ubuntu 17.10 corrupting BIOS - many LENOVO laptops models (LP: #1734147)
    - [Config] CONFIG_SPI_INTEL_SPI_PLATFORM=n"

That being said, this kernel does NOT load the SPI drivers at all and will not suffer from this bug.

Do note that linux-*-generic packages are from a different source package (linux-meta) and as such has a slightly different version number.
