Description
A vulnerability in the Linux kernel's mac80211 WiFi subsystem involves improper offloading of traffic control (TC) setup on AP_VLAN virtual interfaces. The issue arises because AP_VLAN interfaces are purely virtual and should not offload TC setup to drivers. The fix rejects TC offload on these interfaces to ensure software handling.
