      "title": "can: bcm: fix stale rx/tx ops after device removal",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: fix stale rx/tx ops after device removal\n\nRX: an RX_SETUP update(!) for an existing op skipped can_rx_register()\nunconditionally, even when a concurrent NETDEV_UNREGISTER had already\ntorn down its registration (op->rx_reg_dev == NULL). 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->rx_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 would strand the op: neither a\nlater TX_SETUP (bcm_find_op()) nor TX_DELETE (bcm_delete_tx_op()) could\never find it again, since both require an exact ifindex match.",
