"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: btmtksdio: Fix kernel oops in btmtksdio_interrupt\n\nFix the following kernel oops in btmtksdio_interrrupt\n\n[ 14.339134] btmtksdio_interrupt+0x28/0x54\n[ 14.339139] process_sdio_pending_irqs+0x68/0x1a0\n[ 14.339144] sdio_irq_work+0x40/0x70\n[ 14.339154] process_one_work+0x184/0x39c\n[ 14.339160] worker_thread+0x228/0x3e8\n[ 14.339168] kthread+0x148/0x3ac\n[ 14.339176] ret_from_fork+0x10/0x30\n\nThat happened because hdev->power_on is already called before\nsdio_set_drvdata which btmtksdio_interrupt handler relies on is not\nproperly set up.\n\nThe details are shown as the below: hci_register_dev would run\nqueue_work(hdev->req_workqueue, &hdev->power_on) as WQ_HIGHPRI\nworkqueue_struct to complete the power-on sequeunce and thus hci_power_on\nmay run before sdio_set_drvdata is done in btmtksdio_probe.\n\nThe hci_dev_do_open in hci_power_on would initialize the device and enable\nthe interrupt and thus it is possible that btmtksdio_interrupt is being\ncalled right before sdio_set_drvdata is filled out.\n\nWhen btmtksdio_interrupt is being called and sdio_set_drvdata is not filled\n, the kernel oops is going to happen because btmtksdio_interrupt access an\nuninitialized pointer."
