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.
