  "summary": "iio: adc: xilinx-xadc: free IRQ before cancelling the unmask worker on unbind",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: adc: xilinx-xadc: free IRQ before cancelling the unmask worker on unbind\n\nThe ZYNQ XADC alarm IRQ handler queues zynq_unmask_work via\nschedule_delayed_work(); that work is cleared by a devm callback.\nRegister the devm callback before devm_request_irq() so the devres LIFO\nteardown frees the IRQ first, ensuring the handler can no longer queue\nwork by the time the workqueue is cleared. Otherwise the handler could\nre-arm the work and run it after the xadc structure has been freed.\n\nThis issue was found by an in-house static analysis tool.",
