CVE-2023-52477: usb: hub: Guard against accesses to uninitialized BOS descriptors

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

usb: hub: Guard against accesses to uninitialized BOS descriptors

Many functions in drivers/usb/core/hub.c and drivers/usb/core/hub.h access fields inside udev->bos without checking if it was allocated and initialized. If usbgetbosdescriptor() fails for whatever reason, udev->bos will be NULL and those accesses will result in a crash:

Fall back to a default behavior if the BOS descriptor isn't accessible and skip all the functionalities that depend on it: LPM support checks, Super Speed capabilitiy checks, U1/U2 states setup.
