"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: cpsw_new: Execute ndo_set_rx_mode callback in a work queue\n\nCommit 1767bb2d47b7 (\"ipv6: mcast: Don't hold RTNL for\nIPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP.\") removed the RTNL lock for\nIPV6_ADD_MEMBERSHIP and MCAST_JOIN_GROUP operations. However, this\nchange triggered the following call trace on my BeagleBone Black board:\n WARNING: net/8021q/vlan_core.c:236 at vlan_for_each+0x120/0x124, CPU#0: rpcbind/496\n RTNL: assertion failed at net/8021q/vlan_core.c (236)\n Modules linked in:\n CPU: 0 UID: 997 PID: 496 Comm: rpcbind Not tainted 6.19.0-rc6-next-20260122-yocto-standard+ #8 PREEMPT\n Hardware name: Generic AM33XX (Flattened Device Tree)\n Call trace:\n unwind_backtrace from show_stack+0x28/0x2c\n show_stack from dump_stack_lvl+0x30/0x38\n dump_stack_lvl from __warn+0xb8/0x11c\n __warn from warn_slowpath_fmt+0x130/0x194\n warn_slowpath_fmt from vlan_for_each+0x120/0x124\n vlan_for_each from cpsw_add_mc_addr+0x54/0xd8\n cpsw_add_mc_addr from __hw_addr_ref_sync_dev+0xc4/0xec\n __hw_addr_ref_sync_dev from __dev_mc_add+0x78/0x88\n __dev_mc_add from igmp6_group_added+0x84/0xec\n igmp6_group_added from __ipv6_dev_mc_inc+0x1fc/0x2f0\n __ipv6_dev_mc_inc from __ipv6_sock_mc_join+0x124/0x1b4\n __ipv6_sock_mc_join from do_ipv6_setsockopt+0x84c/0x1168\n do_ipv6_setsockopt from ipv6_setsockopt+0x88/0xc8\n ipv6_setsockopt from do_sock_setsockopt+0xe8/0x19c\n do_sock_setsockopt from __sys_setsockopt+0x84/0xac\n __sys_setsockopt from ret_fast_syscall+0x0/0x5\n\nThis trace occurs because vlan_for_each() is called within\ncpsw_ndo_set_rx_mode(), which expects the RTNL lock to be held.\nSince modifying vlan_for_each() to operate without the RTNL lock is not\nstraightforward, and because ndo_set_rx_mode() is invoked both with and\nwithout the RTNL lock across different code paths, simply adding\nrtnl_lock() in cpsw_ndo_set_rx_mode() is not a viable solution.\n\nTo resolve this issue, we opt to execute the actual processing within\na work queue, following the approach used by the icssg-prueth driver."
