CVE-2026-89955

A NULL pointer dereference vulnerability exists in the Linux kernel's s390/vfio-ap module. The race occurs when vfio_ap_mdev_probe_queue() creates the sysfs attribute group before the queue's driver data is set; a concurrent read of the status attribute then retrieves NULL via dev_get_drvdata() a...
