I've updated the book at r12.1-108-gd4208d0bc8 but some necessary information for the SA (mainly, the affected CPUs and if a kernel update is needed besides the microcode update) is not disclosed yet. Leaving this open for the SA.

CVE-2023-28746 ("RFDS") fix needs a kernel update.

Replying to Xi Ruoyao:

CVE-2023-28746 ("RFDS") fix needs a kernel update.

And oops, it also affects the E cores of Alder Lake and Raptor Lake.

The affected processor lists are long, thus I'll list them in "models" from lscpu output.

CVE-2023-39368 (INTEL-SA-00972) is affecting models 191, 190, 183 (only stepping 1, and except Xeon E processors), 154 (except Atom processors), 151, 143 (except "Sapphire Rapids Edge Enhanced" processors).
