nfc: nci: Fix uninit-value in nci_rx_work
[ Upstream commit e4a87abf588536d1cdfb128595e6e680af5cf3ed ]
syzbot reported the following uninit-value access issue [1]
nci_rx_work() parses received packet from ndev->rx_q. It should be
validated header size, payload size and total packet size before
processing the packet. If an invalid packet is detected, it should be
silently discarded.
Fixes: d24b03535e5e ("nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet")
