CVE-2026-31759

CVE-2026-31759 affects the Linux kernel USB ULPI path (usb: ulpi) where a double free could occur in ulpi_register_interface() after a failed device_register(), because the error path freed ulpi twice. The root cause is a missing delegation of cleanup to put_device() via ulpi_dev_release(), preve...
