Vulnerability from github – Published: 2025-05-01 15:31 – Updated: 2025-11-11 03:30In 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(&smc_net_stat_ops) is called without any error handling. If it fails, registering of &smc_net_ops won't be reverted. And if smc_nl_init() fails, &smc_net_stat_ops itself won't 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+0x1b9/0x5f0 Call Trace: register_pernet_subsys+0x29/0x40 ebtables_init+0x58/0x1000 [ebtables] ...
