In the Linux kernel, the following vulnerability has been resolved:
net: nfc: fix races in nfc_llcp_sock_get() and nfc_llcp_sock_get_sn()
Sili Luo reported a race in nfc_llcp_sock_get(), leading to UAF.
Getting a reference on the socket found in a lookup while
holding a lock should happen before releasing the lock.
nfc_llcp_sock_get_sn() has a similar problem.
Finally nfc_llcp_recv_snl() needs to make sure the socket
found by nfc_llcp_sock_from_sn() does not disappear.
