Summary
nfc: nci: free skb on nci_transceive early error paths
Details

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

nfc: nci: free skb on nci_transceive early error paths

nci_transceive() takes ownership of the skb passed by the caller, but the -EPROTO, -EINVAL, and -EBUSY error paths return without freeing it.

Due to issues clearing NCI_DATA_EXCHANGE fixed by subsequent changes the nci/nci_dev selftest hits the error path occasionally in NIPA, and kmemleak detects leaks:
