Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nfc: nxp-nci: Fix potential memory leak in nxp_nci_send()<br /> <br /> nxp_nci_send() will call nxp_nci_i2c_write(), and only free skb when<br /> nxp_nci_i2c_write() failed. However, even if the nxp_nci_i2c_write()<br /> run succeeds, the skb will not be freed in nxp_nci_i2c_write(). As the<br /> result, the skb will memleak. nxp_nci_send() should also free the skb<br /> when nxp_nci_i2c_write() succeeds.
