  "title": "nfc: nci: free skb on nci_transceive early error paths",
  "description": "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:  unreferenced object 0xff11000015ce6a40 (size 640):   comm \u0022nci_dev\u0022, pid 3954, jiffies 4295441246   hex dump (first 32 bytes):     6b 6b 6b 6b 00 a4 00 0c 02 e1 03 6b 6b 6b 6b 6b  kkkk.......kkkkk     6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b  kkkkkkkkkkkkkkkk   backtrace (crc 7c40cc2a):     kmem_cache_alloc_node_noprof\u002B0x492/0x630     __alloc_skb\u002B0x11e/0x5f0     alloc_skb_with_frags\u002B0xc6/0x8f0     sock_alloc_send_pskb\u002B0x326/0x3f0     nfc_alloc_send_skb\u002B0x94/0x1d0     rawsock_sendmsg\u002B0x162/0x4c0     do_syscall_64\u002B0x117/0xfc0",
