  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: airoha: npu: cancel wdt_work after releasing the WDT IRQ\n\nairoha_npu_remove() calls cancel_work_sync() on each core's wdt_work,\nbut the watchdog IRQ that queues it is requested with devm_request_irq()\nand is freed only after .remove() returns.  airoha_npu_wdt_handler() can\ntherefore schedule_work() again once the cancel has returned.  struct\nairoha_npu, which contains the work, is devm_kzalloc()'d and is freed in\nthat same unwind, so the late work dereferences freed memory.\n\nRegister the work with devm_work_autocancel() before devm_request_irq()\nand drop .remove().  Devres runs in reverse order, so the IRQ is freed\nbefore cancel_work_sync(), including when probe fails.  A cancel left in\n.remove() cannot get that order.  Initializing the work first also stops\na pending watchdog interrupt from queuing an uninitialized work item.\nProbe currently calls INIT_WORK() only after devm_request_irq().\n\nThis issue was identified during our ongoing static-analysis research\nwhile reviewing kernel code.",
