Summary
In the Linux kernel, the following vulnerability has been resolved:
nfc: nci: complete pending data exchange on device close
In nci_close_device(), complete any pending data exchange before
closing. The data exchange callback (e.g.
rawsock_data_exchange_complete) holds a socket reference.
NIPA occasionally hits this leak:
unreferenced object 0xff1100000f435000 (size 2048):
comm "nci_dev", pid 3954, jiffies 4295441245
