"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nbonding: fix devconf_all NULL dereference when IPv6 is disabled\n\nWhen booting with the 'ipv6.disable=1' parameter, the devconf_all is\nnever initialized because inet6_init() exits before addrconf_init() is\ncalled which initializes it. bond_send_validate(), however, will still\ncall bond_ns_send_all() even ipv6 is indeed disabled. It will lead to\nNULL derefence of net->ipv6.devconf_all in ip6_pol_route().\n\n BUG: kernel NULL pointer dereference, address: 000000000000000c\n [...]\n Workqueue: bond0 bond_arp_monitor [bonding]\n RIP: 0010:ip6_pol_route+0x69/0x480\n [...]\n Call Trace:\n <TASK>\n ? srso_return_thunk+0x5/0x5f\n ? __pfx_ip6_pol_route_output+0x10/0x10\n fib6_rule_lookup+0xfe/0x260\n ? wakeup_preempt+0x8a/0x90\n ? srso_return_thunk+0x5/0x5f\n ? srso_return_thunk+0x5/0x5f\n ? sched_balance_rq+0x369/0x810\n ip6_route_output_flags+0xd7/0x170\n bond_ns_send_all+0xde/0x280 [bonding]\n bond_ab_arp_probe+0x296/0x320 [bonding]\n ? srso_return_thunk+0x5/0x5f\n bond_activebackup_arp_mon+0xb4/0x2c0 [bonding]\n process_one_work+0x196/0x370\n worker_thread+0x1af/0x320\n ? srso_return_thunk+0x5/0x5f\n ? __pfx_worker_thread+0x10/0x10\n kthread+0xe3/0x120\n ? __pfx_kthread+0x10/0x10\n ret_from_fork+0x199/0x260\n ? __pfx_kthread+0x10/0x10\n ret_from_fork_asm+0x1a/0x30\n </TASK>\n\nFix this by adding ipv6_mod_enabled() condition check in the caller."
