"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nregulator: tps65219: fix irq_data.rdev not being assigned\n\nCommit 64a6b577490c (\"regulator: tps65219: Remove debugging helper\nfunction\") removed the tps65219_get_rdev_by_name() helper along with\nthe irq_data.rdev assignment that depended on it. This left\nirq_data.rdev uninitialized for all IRQs, causing undefined behavior\nwhen regulator_notifier_call_chain() is called from the IRQ handler:\n\n Internal error: Oops: 0000000096000004\n pc : regulator_notifier_call_chain\n lr : tps65219_regulator_irq_handler\n Call trace:\n regulator_notifier_call_chain\n tps65219_regulator_irq_handler\n handle_nested_irq\n regmap_irq_thread\n irq_thread_fn\n irq_thread\n kthread\n ret_from_fork\n\nInstead of restoring a dedicated lookup array, restructure the probe\nfunction to combine regulator registration with IRQ registration in\nthe same loop. This way the rdev returned by devm_regulator_register()\nis naturally available for assigning to irq_data.rdev without any\nauxiliary data structure.\n\nNon-regulator IRQs (SENSOR, TIMEOUT) that don't correspond to any\nregistered regulator are registered with rdev=NULL, and the IRQ handler\nis protected with a NULL check to avoid crashing."
