Description Nick Tait 2024-02-08 17:39:59 UTC 
A flaw found for the AMD CPU. Improper Access Control in the AMD SPI protection feature may allow a user with Ring0 (kernel mode) privileged access to bypass protections potentially resulting in loss of integrity and availability.

Created linux-firmware tracking bugs for this issue:

Affects: fedora-all [bug 2264236]
Comment 6 Peter Robinson 2024-02-25 14:06:31 UTC 
This is a UEFI firmware update from the device vendor, not an update in linux-firmware, these should be closed out as such.
