Linux hwe edge: In the Linux kernel, the following vulnerability has been resolved: regulator: tps65219: fix irq_data.rdev not being assigned Commit 64a6b577490c… (CVE-2026-64230)CVE-2026-64230 0 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.
