Comment 1 Peter Robinson 2024-07-29 11:52:59 UTC 
PKfail isn't part of linux-firmware, it's device UEFI early boot firmware, that is *NEVER* shipped as part of linux-firmware, which provides peripheral device firmware like GPU and WiFi firmware.

The PrivateKey was a AMI key.

This bug is actually completely wrong, it can't addressed by updating linux-firmware, it can only be addressed by updated early boot firmware which could be updated using fwupdmgr if supported by the device.

Can we please do some research on firmware security bugs and how they related  to linux-firmware as we have of late been getting a *LOT* of false positives by Red Hat security response.
