"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ncan: bcm: fix locking for bcm_op runtime updates\n\nCommit c2aba69d0c36 (\"can: bcm: add locking for bcm_op runtime updates\")\nadded a locking for some variables that can be modified at runtime when\nupdating the sending bcm_op with a new TX_SETUP command in bcm_tx_setup().\n\nUsually the RX_SETUP only handles and filters incoming traffic with one\nexception: When the RX_RTR_FRAME flag is set a predefined CAN frame is\nsent when a specific RTR frame is received. Therefore the rx bcm_op uses\nbcm_can_tx() which uses the bcm_tx_lock that was only initialized in\nbcm_tx_setup(). Add the missing spin_lock_init() when allocating the\nbcm_op in bcm_rx_setup() to handle the RTR case properly."
