Title
can: bcm: fix stale rx/tx ops after device removal
Summary
In the Linux kernel, the following vulnerability has been resolved: can: bcm: fix stale rx/tx ops after device removal RX: an RX_SETUP update(!) for an existing op skipped can_rx_register() unconditionally, even when a concurrent NETDEV_UNREGISTER had already torn down its registration (op->rx_reg_dev == NULL). This silently did not re-enable frame delivery for that updated filter. bcm_rx_setup() now re-registers in that case, while leaving rx_ops with ifindex = 0 (all CAN devices) which never carry a tracked rx_reg_dev registered as-is. TX: bcm_notify() only handled bo->rx_ops on NETDEV_UNREGISTER, leaving tx_ops with an active cyclic transmission re-arming its hrtimer indefinitely to execute bcm_tx_timeout_handler(). Cancelling the hrtimer prevents the runaway timer and any injection into a later reused ifindex, since nothing else calls bcm_can_tx() for the op until an explicit TX_SETUP update re-arms it. Unlike bcm_rx_unreg(), which clears the tracked rx_reg_dev for rx_ops, the ifindex is intentionally left unchanged for tx_ops. bcm_tx_setup() always rejects ifindex 0, so clearing it would strand the op: neither a later TX_SETUP (bcm_find_op()) nor TX_DELETE (bcm_delete_tx_op()) could ever find it again, since both require an exact ifindex match.

This silently\\ndid not re-enable frame delivery for that updated filter. bcm_rx_setup()\\nnow re-registers in that case, while leaving rx_ops with ifindex = 0\\n(all CAN devices) which never carry a tracked rx_reg_dev registered as-is.\\n\\nTX: bcm_notify() only handled bo-\u003erx_ops on NETDEV_UNREGISTER, leaving\\ntx_ops with an active cyclic transmission re-arming its hrtimer\\nindefinitely to execute bcm_tx_timeout_handler(). Cancelling the hrtimer\\nprevents the runaway timer and any injection into a later reused ifindex,\\nsince nothing else calls bcm_can_tx() for the op until an explicit\\nTX_SETUP update re-arms it.\\n\\nUnlike bcm_rx_unreg(), which clears the tracked rx_reg_dev for rx_ops,\\nthe ifindex is intentionally left unchanged for tx_ops. bcm_tx_setup()\\nalways rejects ifindex 0, so clearing it
