In the Linux kernel, the following vulnerability has been resolved:
smc: Use __sk_dst_get() and dst_dev_rcu() in smc_clc_prfx_match().
smc_clc_prfx_match() is called from smc_listen_work() and
not under RCU nor RTNL.
Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dst_dev_rcu().
Note that the returned value of smc_clc_prfx_match() is not
used in the caller.
