In the Linux kernel, the following vulnerability has been resolved:

wifi: brcmfmac: fix potential memory leak in brcmf_netdev_start_xmit()

The brcmf_netdev_start_xmit() returns NETDEV_TX_OK without freeing skb
in case of pskb_expand_head() fails, add dev_kfree_skb() to fix it.
Compile tested only.
