Summary
In the Linux kernel, the following vulnerability has been resolved: nfc: fdp: Fix potential memory leak in fdp_nci_send() fdp_nci_send() will call fdp_nci_i2c_write that will not free skb in the function. As a result, when fdp_nci_i2c_write() finished, the skb will memleak. fdp_nci_send() should free skb after fdp_nci_i2c_write() finished.
