  "description": "In the Linux kernel, the following vulnerability has been resolved:  iio: adc: spear: Initialize completion before requesting IRQ  In the report from Jaeyoung Chung:  \u0022spear_adc_probe() in drivers/iio/adc/spear_adc.c registers its interrupt handler with devm_request_irq() before it initializes st-\u003Ecompletion with init_completion(). If an interrupt arrives after devm_request_irq() and before init_completion(), the handler calls complete() on an uninitialized completion, causing a kernel panic.  The probe path, in spear_adc_probe():      iodev = devm_iio_device_alloc(\u0026pdev-\u003Edev, sizeof(*st)); /* st kzalloc-zeroed */     ...     retval = devm_request_irq(\u0026pdev-\u003Edev, irq, spear_adc_isr, 0,                               LPC32XXAD_NAME, st);           /* register handler */     ...     init_completion(\u0026st-\u003Ecompletion);                       /* initialize completion */  spear_adc_isr() calls complete():      complete(\u0026st-\u003Ecompletion);  If the device raises an interrupt before init_completion() runs, complete() acquires the uninitialized wait.lock and walks the zeroed task_list in swake_up_locked(). The zeroed task_list makes list_empty() return false, so swake_up_locked() dereferences a NULL list entry, triggering a KASAN wild-memory-access.\u0022  Fix the chance of a spurious IRQ causing an uninitialized pointer dereference by moving init_completion() above devm_request_irq().",
