  "title": "net: airoha: npu: cancel wdt_work after releasing the WDT IRQ",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  net: airoha: npu: cancel wdt_work after releasing the WDT IRQ  airoha_npu_remove() calls cancel_work_sync() on each core\u0027s wdt_work, but the watchdog IRQ that queues it is requested with devm_request_irq() and is freed only after .remove() returns.  airoha_npu_wdt_handler() can therefore schedule_work() again once the cancel has returned.  struct airoha_npu, which contains the work, is devm_kzalloc()\u0027d and is freed in that same unwind, so the late work dereferences freed memory.  Register the work with devm_work_autocancel() before devm_request_irq() and drop .remove().  Devres runs in reverse order, so the IRQ is freed before cancel_work_sync(), including when probe fails.  A cancel left in .remove() cannot get that order.  Initializing the work first also stops a pending watchdog interrupt from queuing an uninitialized work item. Probe currently calls INIT_WORK() only after devm_request_irq().  This issue was identified during our ongoing static-analysis research while reviewing kernel code.",
