Notes

rodrigo-zaiden

while it is not clear in the advisory, the understanding is that this is a firmware update on the linux-firmware package, which is what being tracked here. I couldn't find which commit on upstream linux-firmware fixes this issue based on the advisory information only.

gianz

the 3168 firmware has not been updated upstream since 2019, so there is no fix for it in any release. resolute: the Intel WiFi firmware ships in the linux-firmware-intel-wireless source.
