CVE-2023-52477

影响性分析说明：
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 usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:

CVE-2023-52477

影响性分析说明：
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 usb_get_bos_descriptor() fails for whatever
reason, udev->bos will be NULL and those accesses will result in a
crash:
