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