Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: avoid possible NULL skb pointer dereference In 'mwifiex_handle_uap_rx_forward()', always check the value returned by 'skb_copy()' to avoid potential NULL pointer dereference in 'mwifiex_uap_queue_bridged_pkt()', and drop original skb in case of copying failure. Found by Linux Verification Center (linuxtesting.org) with SVACE.
