Comment 1 Pedro Sampaio 2021-08-18 16:41:04 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1995237]
Comment 2 Justin M. Forbes 2021-08-18 19:43:08 UTC 
This is not in kernel code, but external drivers available from Intel.
Comment 3 Wade Mealing 2021-08-19 03:05:15 UTC 
@Jforbes, thats what i thought too.. however upstream intel shares quite a lot of structure with the 'ice' kernel module in the kernel.  Intel security team has been contacted awaiting their reply on more specific details as there is insufficient data to draw accurate conclusions at this time.

If you have evidence supporting otherwise, happy to hear it.
Comment 5 Wade Mealing 2021-08-26 00:59:54 UTC 
Its been 7 days and three emails with no data from intel regarding these flaws and if they affect the upstream release.  If they get back to me with data I'll re-open the flaws.  Till then I'll mark notaffected as I do not have sufficient information to state affectedness.
