      "title": "can: bcm: track a single source interface for ANYDEV timeout/throttle ops",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: track a single source interface for ANYDEV timeout/throttle ops\n\nAn ANYDEV rx op (ifindex == 0) with an active RX timeout and/or\nthrottle timer has no defined semantics when matching frames arrive\nfrom several interfaces: bcm_rx_handler() can run concurrently for\nthe same op on different CPUs, racing hrtimer_cancel()/\nbcm_rx_starttimer() against bcm_rx_timeout_handler() and causing\nspurious RX_TIMEOUT notifications and last_frames corruption. The\nsame concurrency lets throttled multiplex frames from different\ninterfaces clobber the single rx_ifindex/rx_stamp fields shared by\nthe op.\n\nAdd op->if_detected to track the first interface that delivers a\nmatching frame while a timeout/throttle timer is configured, and\nreject frames from any other interface for that op. The claim is\ndecided in bcm_rx_handler() before hrtimer_cancel() touches\nop->timer, so a rejected frame can never disturb the claimed\ninterface's watchdog. RTR-mode ops are excluded via RX_RTR_FRAME,\nindependent of kt_ival1/kt_ival2, since those may briefly hold a\nstale value from an earlier non-RTR configuration.\n\nThe claim is released in bcm_notify() on NETDEV_UNREGISTER and in\nbcm_rx_setup() when SETTIMER reconfigures the timer values.\n\nA (re-)claim is only possible on CAN devices in NETREG_REGISTERED\ndev->reg_state to cover the release in bcm_notify() where reg_state\nbecomes NETREG_UNREGISTERING until synchronize_net().",
