Comment 1 Pedro Sampaio 2021-08-18 16:43:55 UTC 
Created kernel tracking bugs for this issue:

Affects: fedora-all [bug 1995244]
Comment 2 Justin M. Forbes 2021-08-18 19:41:45 UTC 
This is not in kernel code, but external drivers available from Intel.
Comment 3 Wade Mealing 2021-08-19 03:05:40 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 4 Wade Mealing 2021-08-19 03:06:34 UTC 
Needinfo'ing you here so that you dont answer in the 3 bugs from the same intel advisory.
Comment 5 Wade Mealing 2021-08-26 01:03:53 UTC 
Its been 7 days with no details from intel, I'll reopen this flaw if intel product security get back to me with specifics.
Comment 6 Red Hat Bugzilla 2023-09-15 01:13:50 UTC
