CVE-2025-68360 (published 2025-12-24)
In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: wed: use proper wed reference in mt76 wed driver callabacks

MT7996 driver can use both wed and wed_hif2 devices to offload traffic
from/to the wireless NIC. In the current codebase we assume to always
use the primary wed device in wed callbacks resulting in the following
crash if the hw runs wed_hif2 (e.g. 6GHz link).
