    "summary": "In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: don't offload TC setup on AP_VLAN interfaces AP_VLAN interfaces are purely virtual, so don't try to offload TC setup to drivers. We can't really use the AP interface either since we may not know it all the time, and it could technically even change. Just reject the TC offload so things get done in software.",
