[PATCHv2 bluetooth-next] mac802154: fakelb: Fix potential NULL pointer dereference.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



fakelb_hw_deliver creates a copy of the skb's header which can
potentially return NULL so we now check for this before actually
delivering to the 802.15.4 MAC layer.
