  "description": "In the Linux kernel, the following vulnerability has been resolved:  net/smc: Fix possible leaked pernet namespace in smc_init()  In smc_init(), register_pernet_subsys(\u0026smc_net_stat_ops) is called without any error handling. If it fails, registering of \u0026smc_net_ops won\u0027t be reverted. And if smc_nl_init() fails, \u0026smc_net_stat_ops itself won\u0027t be reverted.  This leaves wild ops in subsystem linkedlist and when another module tries to call register_pernet_operations() it triggers page fault:  BUG: unable to handle page fault for address: fffffbfff81b964c RIP: 0010:register_pernet_operations\u002B0x1b9/0x5f0 Call Trace:   \u003CTASK\u003E   register_pernet_subsys\u002B0x29/0x40   ebtables_init\u002B0x58/0x1000 [ebtables]   ...",
