| parent | llc: fix skb UAF and leaks on llc_mac_hdr_init() failure (diff) | |
bridge: check llc_mac_hdr_init() return value in br_send_bpdu()
If llc_mac_hdr_init() fails (for instance if the port device type does
not support LLC or dev_hard_header() fails), br_send_bpdu() should drop
the skb instead of resetting the mac header to the LLC payload and
transmitting a malformed frame.
