Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> usb: dwc3: host: Stop setting the ACPI companion<br /> <br /> It is no longer needed. The sysdev pointer is now used when<br /> assigning the ACPI companions to the xHCI ports and USB<br /> devices.<br /> <br /> Assigning the ACPI companion here resulted in the<br /> fwnode-&gt;secondary pointer to be replaced also for the parent<br /> dwc3 device since the primary fwnode (the ACPI companion)<br /> was shared. That was unintentional and it created potential<br /> side effects like resource leaks.
