CVE-2026-64230

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> regulator: tps65219: fix irq_data.rdev not being assigned<br /> <br /> Commit 64a6b577490c ("regulator: tps65219: Remove debugging helper<br /> function") removed the tps65219_get_rdev_by_name() helper along with<br /> the irq_data.rdev assignment that depended on it. This left<br /> irq_data.rdev uninitialized for all IRQs, causing undefined behavior<br /> when regulator_notifier_call_chain() is called from the IRQ handler:<br /> <br /> Internal error: Oops: 0000000096000004<br /> pc : regulator_notifier_call_chain<br /> lr : tps65219_regulator_irq_handler<br /> Call trace:<br /> regulator_notifier_call_chain<br /> tps65219_regulator_irq_handler<br /> handle_nested_irq<br /> regmap_irq_thread<br /> irq_thread_fn<br /> irq_thread<br /> kthread<br /> ret_from_fork<br /> <br /> Instead of restoring a dedicated lookup array, restructure the probe<br /> function to combine regulator registration with IRQ registration in<br /> the same loop. This way the rdev returned by devm_regulator_register()<br /> is naturally available for assigning to irq_data.rdev without any<br /> auxiliary data structure.<br /> <br /> Non-regulator IRQs (SENSOR, TIMEOUT) that don&amp;#39;t correspond to any<br /> registered regulator are registered with rdev=NULL, and the IRQ handler<br /> is protected with a NULL check to avoid crashing.
