Summary
net/smc: Fix possible leaked pernet namespace in smc_init()
Details

In the Linux kernel, the following vulnerability has been resolved:

net/smc: Fix possible leaked pernet namespace in smc_init()

In smcinit(), registerpernetsubsys(&smcnetstatops) is called without any error handling. If it fails, registering of &smcnetops won't be reverted. And if smcnlinit() fails, &smcnetstat_ops itself won't be reverted.

This leaves wild ops in subsystem linkedlist and when another module tries to call registerpernetoperations() it triggers page fault:

BUG: unable to handle page fault for address: fffffbfff81b964c RIP: 0010:registerpernetoperations+0x1b9/0x5f0 Call Trace: <TASK> registerpernetsubsys+0x29/0x40 ebtables_init+0x58/0x1000 [ebtables] ...
