In the Linux kernel, the following vulnerability has been resolved:

can: bcm: add missing rcu list annotations and operations

sashiko-bot remarked the missing use of list_add_rcu() in

bcm_[rx|tx]_setup() to have a proper initialized bcm_op structure

when bcm_proc_show() traverses the bcm_op's under rcu_read_lock().

To cover all initial settings of the bcm_op's the list_add_rcu() calls

are moved to the end of the setup code.

While at it, also fix the mirroring removal side: bcm_release() called

bcm_remove_op() - which frees the op via call_rcu() - on ops that were

still linked in bo->tx_ops/bo->rx_ops, without list_del_rcu() first.

Unlink each op with list_del_rcu() before handing it to bcm_remove_op(),

matching the existing pattern in bcm_delete_tx_op()/bcm_delete_rx_op(). (NVD)
