Title
wifi: mac80211: don't offload TC setup on AP_VLAN interfaces
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.
Severity
No CVSS data available.
