  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\niio: temperature: tmp006: use devm_iio_trigger_register\n\ntmp006_probe() allocates the DRDY trigger with devm_iio_trigger_alloc()\nbut registers it with plain iio_trigger_register(). The driver has no\n.remove() callback, so on module unload the trigger stays in the global\ntrigger list while its memory is freed by devm, leaving a dangling\nentry.\n\nSwitch to devm_iio_trigger_register() so the registration is undone in\nthe same devm scope as the allocation.",
