Ryosuke Yasuoka a946ebee45 nfc: nci: Fix uninit-value in nci_dev_up and nci_ntf_packet ... [ Upstream commit d24b03535e5eb82e025219c2f632b485409c898f ] syzbot reported the following uninit-value access issue [1][2]: nci_rx_work() parses and processes received packet. When the payload length is zero, each message type handler reads uninitialized payload and KMSAN detects this issue. The receipt of a packet with a zero-size payload is considered unexpected, and therefore, such packets should be silently discarded. This patch resolved this issue by checking payload size before calling each message type handler codes.
