Official description

In the Linux kernel, the following vulnerability has been resolved: nfc: nfcmrvl: Fix potential memory leak in nfcmrvl_i2c_nci_send() nfcmrvl_i2c_nci_send() will be called by nfcmrvl_nci_send(), and skb should be freed in nfcmrvl_i2c_nci_send(). However, nfcmrvl_nci_send() will only free skb when i2c_master_send() return >=0, which means skb will memleak when i2c_master_send() failed. Free skb no matter whether i2c_master_send() succeeds.
