"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/ap: use generic driver_override infrastructure\n\nWhen the AP masks are updated via apmask_store() or aqmask_store(),\nap_bus_revise_bindings() is called after ap_attr_mutex has been\nreleased.\n\nThis calls __ap_revise_reserved(), which accesses the driver_override\nfield without holding any lock, racing against a concurrent\ndriver_override_store() that may free the old string, resulting in a\npotential UAF.\n\nFix this by using the driver-core driver_override infrastructure, which\nprotects all accesses with an internal spinlock.\n\nNote that unlike most other buses, the AP bus does not check\ndriver_override in its match() callback; the override is checked in\nap_device_probe() and __ap_revise_reserved() instead.\n\nAlso note that we do not enable the driver_override feature of struct\nbus_type, as AP - in contrast to most other buses - passes \"\" to\nsysfs_emit() when the driver_override pointer is NULL. Thus, printing\n\"\\n\" instead of \"(null)\\n\".\n\nAdditionally, AP has a custom counter that is modified in the\ncorresponding custom driver_override_store()."
