What it is

In the Linux kernel, the following vulnerability has been resolved:

usb: dwc3: host: Stop setting the ACPI companion

It is no longer needed. The sysdev pointer is now used when

assigning the ACPI companions to the xHCI ports and USB

devices.

Assigning the ACPI companion here resulted in the

fwnode->secondary pointer to be replaced also for the parent

dwc3 device since the primary fwnode (the ACPI companion)

was shared. That was unintentional and it created potential

side effects like resource leaks.
