bcm: add missing rcu list annotations and operations","description":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: add missing rcu list annotations and operations\n\nsashiko-bot remarked the missing use of list_add_rcu() in\nbcm_[rx|tx]_setup() to have a proper initialized bcm_op structure\nwhen bcm_proc_show() traverses the bcm_op's under rcu_read_lock().\n\nTo cover all initial settings of the bcm_op's the list_add_rcu() calls\nare moved to the end of the setup code.\n\nWhile at it, also fix the mirroring removal side: bcm_release() called\nbcm_remove_op() - which frees the op via call_rcu() - on ops that were\nstill linked in bo->tx_ops/bo->rx_ops, without list_del_rcu() first.\nUnlink each op with list_del_rcu() before handing it to bcm_remove_op(),\nmatching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op().","state":0,"publishedAt":"2026-08-15T05:52:59.226+00:00","modifiedAt":"2026-10-16T18:44:57.136+00:00","affected":[{"ecosystem":"Vendor
