A unicast frame sent on one\ninterface thus matches a station of a different VLAN of the same BSS and\nis transmitted to it.\n\nOnly match stations of the interface the frame is sent on, except for\ncontrol port frames, since those may be sent for VLAN stations directly\non the BSS interface.","state":0,"publishedAt":"2026-10-18T15:49:14.593+00:00","modifiedAt":"2026-10-21T12:57:13.743+00:00","affected":[{"ecosystem":"Vendor
