Comment 1 Marco Benatto 2024-03-21 15:27:34 UTC
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 2270735]

Comment 4 Justin M. Forbes 2024-03-25 19:16:35 UTC
"Intel is releasing a firmware update to mitigate this potential vulnerability."
And again, another microcode, not kernel.
